You'd be pissed if you hit someone and then went to war and they retalled? Give me a break. Going to war doesn't give you the right to hit whoever you want outside of it and be immune.
Regarding it being a mistake: Nope there was no mistake. When I asked octobrev about it he told me what happened: Folle hit him, and then declared on a kingdom that the largest person was roughly 33% his size. When I asked his kingdommates later if this was a planned war, they told me that the monarch just does whatever he wants without telling them. They later aided us in his removal. Guy is just filth in every aspect of the game.
