latest.log

I am playing on the Valhelsia 3 modpack and the pack just updated. I am not sure if this is the reason why my builder decided to bug out, but they did. I recalled the worker, restarted the game, and restarted the worker as well. I could not fire them, the button is grayed out. The message just says, " My AI has run into an issue, please locate the latest.log file and send it to the Minecolonies authors with this message.

Let me know what else you need.

I've got the same issue. Valhelsia 3 modpack when I try to have the builder upgrade their hut, it gives me the same error.

Update to the newest alpha

something corrupted your colony from loading then, you can try the loadbackup command

okay updating to the newest version fixed the issue on a single player world. but after updating on the server, all of the buildings say they don't have a respective building and i don't own the colony anymore
