As seen, I survive the trap damage and continue bashing it open.

I break it open, get 119 gold from it, and try to rest. Exertion stops me, but that clears in a moment, only for...

This! The chest kills me somehow; no damage applied, no reason given, just death. Off I go to Fugue.
What happened? If this is supposed to happen for whatever reason, I apologize, but just... what?
