When the next rogue had his favourite awesome greatsword taken out of his hands by some sort of magic trap halfway down an unmarked corridor with no means of retrieving it, (even though he saw it slowly floating away help by an invisible force hand) that was not cool, and the player, citing other reasons, did not come back the next week, or until we started a new game. I do not blame him.
I'm not overly familiar with the module. Are you sure that there was no means of retrieving it?
I would consider things like "You didn't check your new bag of holding to see if it had rust monsters in it because you didn't say you did" to be somewhat similar.
It boggles my mind. I have a hard time imagining a player, anywhere, ever, finding a bag and not first asking "Is there anything in it?"
