"In a multiplayer server someone accidentally summoned him early and ended up getting us all killed. This caused the bug where his human form doesn't respawn effectively "locking" the dungeon for good. Someone came up with an idea to lure one of the night time skulls (avoiding instant gib of daytime) and killing that above ground with the team. He accidentally brought 2, which we killed (getting the defeated message each time) and much to our surprise it actually unlocked the dungeon."
