Update: The fix is live in version 1.1.0. Thank you all for your patience! I will continue to monitor this behavior just to make sure all is OK.
Hey, all! I want to warn you that a critical bug is found when your troops are diminished before entering battle but the hex battle doesn't result in defeat.
I am actively working on a fix, expect it by the end of today for both PC and Mac! I apologize for any inconvenience that this might cause! Until a fix is presented, you may use your checkpoints in case you stumble upon the issue and try to keep your troops alive till the end :)
