Tonight's build includes the optimizations I've talked about in the previous announcements. The system mostly works best when you have a large town but should improve overall performance too.
I'm also working on some more options in the Settings UI to improve performance on lower-spec PCs even more.
This build also includes a fix for the issue of Workers sometimes getting stuck walking in a loop when outside of town and looking for a tree to chop down and a new Hammer shaped mouse cursor!
