Reproduction:

When you grab a slime it'll clip through a wall to stack on top of another

happens with all mobs that normally can't pass the barrier too, happens because the game makes the mob ignore all shield checks when you are grabbing it (so you can drag the mob to the barrier, wouldn't want a wall
