QuoteAttack from rope or parachute (AFR) (AFC): You can only attack while hanging on a rope or while using your parachute, unless the weapon that you're using doesn't permit that.
If you break any of the rules mentioned above (WBA, CBA, AFR) you must not attack your opponent durin g your next turn, but you're still allowed to get your crate.
This is for you, Berria, since you didn't seem to know about AFR/AFC.
I'm still inclined to void the game though; you only did 15 damage and you were leading by quite a lot and there's no rule about not skipping your turn after a cow means you lose (though there should be)
Moderator discretion, I guess

Perhaps another mod would like to give his opinion if he disagrees
