Expected Result: Hitbox should be approximately the visual size
Observed Result: Magma Cubes seem to have a hitbox much larger than their actual visual size. They are able to seemingly float on air.
Steps to recreate: As seen in the attached image, I have a 2x2 block area that the magma cube should fall through, but doesn't because it's massive hitbox is clipped onto the corner of a nearby netherrack block.
DISREGARD. the magma cubes were spawned by commands. after looking at the magma cube's vanilla files, I found that the command I spawned it with bypassed "minecraft:entity_spawned", so it never got its collision_box updated it seems. in normal survival gameplay you would never encounter this bug, only if you spawned them by commands.
I can't delete reports so this will stay up.
