Puzzle items in dungeons should either respawn or be lootable by the whole party, otherwise you run the chance of one griefer exiting or not complying with the dungeon mechanics and ruining it for everyone else. Not to mention if you've got a friend (aherm... Dara) that suffers from disconnects and can't get back in.
I gotta agree with this. The Cloak Tower is frustrating when one player leaves at the end taking his piece with him either intentionally or without realizing you need to place them on the pedestals to open the chests. You do a re-run to see what you missed and find the piece has already been picked up.
