Thanks to plenty of reports from everyone kind enough to help us test, we've identified a very common crash in the most recent beta test (V0.2112). It was to do with creatures spawning underground and therefore affected just about every level, eventually. Due to lots of people very kindly taking the time to send in their crash reports to us it took us practically no time to identify the issue - this is a hotfix for the currently running beta to fix this issue only.
Patch Notes
- Fixed a crash caused by any creatures not belonging to the player colony spawning underground or entering the nest
If you're currently participating in the beta your game should update automatically to fix this issue. Again, thank you to everyone who helped us - you made finding this issue super easy.
