Release v2.1.3 is now out. It has a few more bugfixes and one change to NPCs. NPCs moving around really didn’t create any interesting situations and having them disappear and turn up just made it harder to keep track of. NPCs will no longer move and new ones will not spawn. They might still disappear, but this is much rarer now.
Important fixes are mainly situations that could block progress in some rare cases. There are still some hard-to-reproduce bugs and probably some that I’m still not aware of. Let me know if you find any.
