- I can't seem to walk. I can take a few normal steps, then I move at a crawl. Kinda like an immediate start stop. Never happened before. (?)

- In Hell, sometimes when I kill a Bone Serpent, it'll still be moving around as just a head but the rest of it's body will be gone. It's head is still possible to kill.

- Angler achievements broken

- Attemping to get into a minecart on a minecart rail through a wall will sometimes shoot a grapple hook. No matter which hook you have equiped it will always be the one sold by the Goblin tinkerer.
