Sorry Squeee
You have entered the twilight zone.

This seems to be the Evony objective. Mindless stupidity pretending to be war.
This isn't sour grapes either. This is what the game is about. Eventually the jughead will stop but it means you need to set production to 0 on everything but food, allocate all warehouse to food, keep tax so you can pay your hero's and wait him out. Sad, rather pathetic but.. this is evony.
