Max Levels for Castles, skins

According to the dialogue the level you are at when the event ends is somehow represented in the skin/outfit of the character. Not sure how it's going to work, but it also stated it wouldn't be visible until AFTER the event ends.

My current character levels

Homer - 37
Marge - 13
Lisa - 23
Bart - 18

Castle Levels

Barbarian Castle - 16
Castle Recycle - 16
Boxingham Palace - 16

and YES, I spent a LOT of donuts.

My gold count is currently at 48,849. I have done a TON of raiding.
