For some strange reason, if a mob is equipped with a shield in the offhand, the Shield will render weirdly while the game is paused. Unpausing the game instantly reverts it back to normal.
NOTE: For some strange reason, this only happens if the mob’s main hand is empty, and the shield is equipped in the offhand. If the mob either has an item in it’s main hand, or has the shield equipped in their main hand instead, this bug does not occur.
How to replicate:
Spawn any mob that can hold a Shield, and equip it on the mob’s off-hand.
Pause the game
Expected Results:
The Shield remains in a normal pose
Actual Result:
The Shield becomes glitched out
