The most prominent bugs I have come across thus far have been my builders getting stuck on tall surfaces due to lack of ladders and eventually dying, my warriors who keep wanting to kill something (even extremely low on health), and (oxford comma) farmers not eating or wanting to eat and continuously walking around in circles not eating til they die.
This is for the developers. Hopefully you see this and do not take it the wrong way… I just want to help fix these bugs because I absolutely ADORE your game xP
