Hi everybody! This update contains basically zero new features, but I still find it extremely exciting! The biggest thing in this new update is actually quite small indeed; the game now uses about 80% less RAM than it used to, especially on big games with lots of subscribers! This means that folks should have a *lot* fewer problems with autosaves and general memory swapping than in previous builds! The biggest saved game I've seen so far was about 60 megabytes in size, and with this change it came down to about 18 megabytes. When loaded into memory, it was taking nearly 10 gigabytes of RAM, and now it's down to 1.5 gigabytes. This is a *huge* improvement, especially for folks (like me!) who don't have 32 gigabytes of RAM in their computers! Here's the full changelog:

• Switched from a precise subscriber knowledge model to an abstract one, which reduced our memory load substantially! Also, we now only store one day's worth of memory and thoughts for each subscriber.
• Dramatically sped up pathfindinding 'obstacle' checks; pathfinding in complicated regions should now be substantially faster than before.
• Fixed a pathfinding bug which caused players to sometimes travel diagonally through the middle of buildings which had been rotated during placement.
• Combat abilities now actually require their specified costs. (no more casting fireballs when you're out of mana!)
