Did the FotD last night the the boss got stuck under the stairs at the main tower, we tried to sail away to fix it and when that didnt worked we used gunpowder barrels and blunderbombs but it didnt worked so we just killed him and we couldnt get the key.
It happened to me way too many times and the solution is so easy why cant we just spawn the key on the floor on the main tower or even ring a bell there in case it got stucked but that might get abused somehow so just drop the key at the main tower instead of dropping it where he died.
An easy fix to a big problem.
