Hi, I think I encountered a bug yesterday. In a 3p game during the harvest, I ate a clay (pottery) and then killed one animal. The "undo" sign appeared but the "go forward" green arrow did not. So I couldn't actually advance through the harvest. Weirdly, this was fixed if I killed the animal first, and then ate the clay.
I think this may have had something to do with my opponent playing Slaughterman? Might there be a slaughterman bug involving the slaughterman needing to harvest last?
