(Important note - if you DO NOT WANT TO OPT INTO P19, then please select P18-frozen from your Steam beta client BEFORE entering the world) And here we are, once again, for the 19th free content patch since leaving Early Access. This patch again delivers a bunch of progress on the Adventures Pack (available before release to Patreons), and I have to say - the Sky Islands gamemode is a lot more fun than I'd imagined! For those of you who watch me stream development, make sure you tune in for the P20 playthrough, as I'll be running as many of new Mutators as I can for bug testing. On top of that, Rooms can now be classified into Filtered, Clean, Hot, Cold and, er, Wet. Wet rooms allow Plants to grow faster, and Hot and Cold rooms allow you to ignore the effects of the Cold Cavern/Magma Caverns. Filtered rooms allow you to ignore the effects of the Toxic Cavern. Clean Rooms will be finalised in P20. There's no current achievement for completing the game without fitting a Suit Heater and Toxic Filter, but it's now - in theory - technically possible. After a 3 year hiatus, the Robot Arms are back and renamed to Robotic Sorters. You can use these to move items from one conveyor to another without slowing the conveyor down, allowing much faster sorting than the current Advanced Conveyor Filters allow, with no backstuffing. They come in 4 tiers, the top tier being Frozen Factory only.
And finally, ARTHER's gained a proper UI (press tab) and SpiderBot can now have Beacons fitted to it, to collect drops when out in the wild.
On with the patch notse!

TL;DR

• SpiderCORs allow SpiderBot to return Pristine drops to base (Feed the base a couple of Beacons)
• Fully-threaded visiblity - FPS get!
• Almost all Mutators implemented (Adventures Pack only)
• Hiveminds now much more... interesting.
• Player gun needs crafting!
• Ore Extractor offline messages now MUCH more accurate and useful!
• Robotic Sorters allow you to collect specific items from Conveyor runs WITHOUT slowing them down
• ARTHER has a proper UI - press Tab! (and yes, it's re-bindable)
• Specific Room types with uses and everything!
• If you're running your Steam Client in a non-English language, the game will default to that language. You can return to English when the main menu starts up.

Known Issues

• Cloning Machine drops you off inside it instead of near it
• Some issues related to Conveyors and Assembly machines; Stampers don't animate, and finish instantly
• Some items are HUGE on Robotic Sorters - this includes all Organic stuff, but won't affect performance or behaviour
• Macerator still shows power, only it doesn't need it.
• Cargo Lift controllers no longer show Tier correctly.
• Manufacturing plants have some items that are visually weird when crafting (Minecarts are one of them)
• Electric Lights are missing SpotlightShadow mode

Important stuff

• Implemented Improved and Advanced Crystal Scanners. These should further aid the player in their discovery of Crystal resources. If you're playing on Rapid mode, you always have access to the Improved scanner, and crafting it will achieve nothing. The Advanced scanner will require Frozen Factory.
• Hive minds have evolved due to player's playstyles, and are much more tightly linked. As if they were a... hive mind, or something. This is designed to be much more 'scary' than 'base-ending', and so far tests have looked great.
• Added SpiderCors, and the ability to load a FALCOR Beacon onto the SpiderBot. This means that SpiderBot should be quite capable of returning Organic Drops from his wildlife murderin'
• Dedicated Server Launcher now works. Like, actually properly works. Use the Tool download in Steam.
• Added Cloning Machine. Use this to set your spawn location, where you die when you die, and where new players on your server will be... spawned!
• Renamed TriSeed to Mandragora.
• Added recipe to craft Crude Organic Lense from Mandragora. YOU DO NOT NEED TO KEEP AN OVERMIND ALIVE FOR LOTS OF LENSES EVER.
• Added new Robotic Sorters. This can collect from a Conveyor in front of them and place onto a Conveyor behind them. Available in 4 tiers, the fastest of which is only part of Frozen Factory.
• CamoBots have evolved to defeat smart-alec player's defences. They haven't worked out a way to defend against a laser turret to the face. Laser turrets : recommended.
• Added Room Coolers; use these to remove any heat penalty from Rooms built within the Magma Caverns.
• Added Room Heaters; use these to remove any heat penalty from Rooms built within the Cold Caverns.
• Rooms with a Greenhouse rating of >100% will cause plants to grow at double speed. There is no current benefit to increasing the rating above 100%
• Added Room Scrubbers and Filters. Filters improve the Clean rating of your room, which will provide various bonuses to machines built in them. Scrubber improve the Bio-Hazard rating of your room, allowing the player to bypass the Toxic Filter cost inside the Toxic Caverns.
• Rooms now re-check validity when the player is inside and building. This should mean near-realtime feedback on additional Scrubbers and Filters.
• Added Room Smoke. Room working fine? No smoke. Room in the Toxic Caverns and not properly Scrubbed? Green smoke. You get the the idea.

QoL

• Logistics FALCORs and Robotics Sorters both support pressing T ("Store") for a quick assignment of the current hotbar item.
• Trenchers now work with signs
• Trenchers now have report on/off toggle
• Trenchers now send issue type/name to alerts
• Ore Extractors now Clear Veins 150 times faster. This is about 18,000 blocks/hour, up from 120 per hour.
• The most-broken Ore Extractor (as listed in your missions, top right) will now be MUCH MORE OBVIOUS on the HoloBase.
• Ore Extractor 'offline' message no longer generic. It will now warn you about badly placed Extractors, ones where the Cutting Head has depleted, ones with no power, ones with no storage and ones where the vein has been depleted. I hope this alleviates literally everyone's complaints.
• "Out of Storage' Ore Extractor warning now suppressed until it's been offline for 30 minutes.
• Added Inversion for Type Filtering on Basic Filters (Thank you Mad Vandal!)
• Room Doors now open from further away, based on some sensible rules.
• [Dapper]Electric Lights now paintable. Light modes should also now cycle on the server.
• Resin is no longer optional to complete the base game.
• Worms health reduced to 150k
• DapperBlocks now count as 'hard', and you'll run fast on them.
• Moved a number of outdated machines behind the 'Mothballed' research. Can't find a machine? Check the research station first!
• Free Induction Plate for Rapid players
• Trusses are now marked as Glass, and shouldn't work as walls, and lasers should go through them
• ARTHER Turret now allows charging to 300%, letting him fire more often, if he's sat in the turret in advance.

Adventures Pack

• [Adventures Pack] "The Floor Is Lava" implemented. Probably you can charge the OET in this mode. Let me know it goes for you. No further details are forthcoming.
• [Adventures Pack]Added a Mesh for the Orbital Railgun
• [Adventures Pack] Improvements to Orbital Railgun construction and feedback
• [Adventures Pack]Robots, when aggressively disassembled, will now pack themselves into a handy-dandy crate. Stick this back in a Robot Constructor to turn it back into a Robot!
• [Adventures Pack]Robots can now have Carrying Arms and Herb Arms. Carrying Arms let them interact with Storage Hoppers and Herb Arms let them automatically harvest grown plants off of Hydroponics Bays.
• [Adventures Pack]Herb Arms (name pending) now require Agriculture research.
• [Adventures Pack]Robomania mode implemented. This is basically an incredible Conveyor nerf.
• [Adventures Pack]Aggressive Mobs mode implemented
• [Adventures Pack]Hardcore Inventory mode implemented. This essentially changes all infinite-stack items to a maximum of 100, and leaves Ore at 150 max. You can also no longer manually-craft - all items crafted via a Manufacturing Plant must be delivered to a hopper, and will require both time and energy to craft.
• (This means that only Hardcore Ceilings, Lucrative Mobs, Purchase Mode and Happy Feet are left)
• [AdventuresPack]Disallowed Paste placement in Sky Islands
• [AdventuresPack]Crystals and Organic rock should spawn in Sky Islands
• [AdventuresPack]Added Organic Detritus to Sky Islands

Frozen Factory

• [FrozenFactory]Fixed issue in CryoMap fade
• [FrozenFactory]Each CryoSpawn Kill will speed up all remaining CryoSpawners; this should (hopefully) mean an escalating challenge for the player
• [FrozenFactory]Dazzler beams no longer disappear when Dazzler is behind you. Less 'surprise death!'
• [FrozenFactory]T4 drills will no longer have 'ghost' heads.
• [FrozenFactory]Dazzler will now correctly store AND transmit the amount of Cyro cleared.

Crafting changes

• Gold Bars are no longer used. Anything manual craft that used to use Gold Bar will now use Gold Wire.
• Titanium Bars are no longer used. Anything manual craft that used to use Titanium Bar will now use Titanium Plates.
• Nickel Bars are no longer used. Anything manual craft that used to use NickelBar will now use Fortified (Nickel) PCBs.
• GACs may still use a variety of items including bars, and these have not changed, so your automation should be just fine.
• MK2 Forced Induction no longer requires Copper Wire. However, this recipe will be rebalanced for the new T1 Ultimate in P20.
• MK3 Forced Induction now uses Alloyed Machine blocks instead of T2 materials.
• MK4 Forced Induction now uses Alloyed Machine blocks instead of T2 materials. Cost is about the same, but it's awful lot simpler to make or automate.
• Added Bulk Mining Upgrades and moved the highest tier of Inductions and Motors into it. Can't craft an item you used to be able to? You're gonna need to research this! (This was changed as Advanced Miner Upgrades gave access to just far too many new items, so it's been split into 2 sections)

Performance

• Added a number of performance improvements related to when you are viewing full-screen menus.(You can tell if these improvements are active, as the world goes blurry)
• Minor optimisation to the usage of Turret CPU when scanning for mobs.
• You can no longer build multiple CCCCC's!
• HoloBase should now be substantially faster to render.
• Fixed Vis issues with Geothermals
• Substantially improved MatterMover render performance
• Magma, Resin and Cryo-only segments now obey vis.
• Research Panel now runs at 60 fps
• Increased network transmission distance of Conveyors, which should significantly increase their sync ratio for clients.
• "Rate 0" for Dedicated Servers is now considered "LAN Mode". First thing to hook to this is that machines such as Conveyors will net-sync at unlimited distance. You can use this on an Internet server, but be aware that you may use up over a 1 gigabyte per player, per hour, on a medium-sized base.

Other
