@TylerGlaiel A redditor found an interesting glitch where they did a solo run with a cat and sacrificed their only cat in the throbbing domain, losing the run, before doing alt+f4 and reloading the save. The result is what you see here and the game crashing afterwards.

The OP said that the collars change every frame, too. It almost sounds like a creepy pasta, lmao.
