Constant Thawzone Exceptions {Beta}

[Former user]

Im meandering around the saltmarches looking for the oddly hued glowfish and Im getting a thawzone exception on every new screen, but not on every old screen. Ive got no idea whats causing it, ive done nothing weird to cause it though except reloading a checkpoint after dying.

need the save directory to repro; probably a mod outdating saves or something
