While testing the new gobbo campaign, I have had a specific error break my game twice in a row now.
Here’s the screenshot of the error:
This error takes some time to develop. Create a shepherd. Give him a good sized pasture (see screenshot for example) and give him a few months to collect sheep. Eventually the error starts appearing.
I am going to try to turn the sheep into food and see if the error goes away (maybe I have too many sheep).
Let me know if you can replicate it.
