Lord Thane When it happened to Haybol, I believe this was after you fixed magic as one of the kingdoms that did the spell was bigger than him, the other was smaller. Also in the aftermath, Haybol was still able to attack both kingdoms and get a castle from each, therefore ending up 2 castles ahead and 1000 buildings lost.
Nolio You (Haybol) were at 57K ks, Katy was at 58.5k ks meaning he was bigger than you, and Goldwood was at 38.5k ks. That said, ouch that looks awful
I agree with Doug that spells might have too much power, same as he pointed out then.
