This update is mainly lots of bug fixing and code cleanup behind the scenes. I also did a smaller v0.5.2.14 update that I didn't make an update post for earlier, which improved CPU performance.

The specifics:

2015-12 - 0.5.2.15
- Added heavy armour part
- Better support for XBox 360 controller on Mac and Linux. Separate default key bindings keep actual inputs the same on all platforms
- Engine sounds with multiple of the same engine work together better
- Removed an annoying ridge in the RiverRift terrain
- Added some subtle fades between scenes
Bug Fixes:
- Fixed occasionally coming back from testing vehicles to the build screen and your vehicle has flown off into space somewhere
- Removed more false positives and not-really-bad words from the swear filter
- "Open save folder" button now working on Linux
- Fixed the loading screen getting stuck if your vehicle spawned in right as a round ended
- Fixed visual glitch between light beams and edge wall glass
- Fixed screen staying white if your vehicle was destroyed right at the moment of evac completion
- Fixed game modifiers (low gravity) not being unapplied on connected clients if the server shut down
- Fixed SkinnedMeshRenderer errors being generated in-game (in the background) if a vehicle had no moving parts
- Lots of refactoring and fixing issues with chassis, propulsion systems and their hit points and other values
- Tooltips for chassis select now include the extra HP gained from the wheels (so they show the actual full chassis HP now)

2015-12 - 0.5.2.14
- CPU performance improvements due to physics and rendering optimisation work
- Tweaks to the RiverRift map layout
- Swedish translation update

Have a good Christmas everyone. I won't be able to join the Weekly Game tomorrow. Thanks everyone who reported bugs that are fixed here.
