My friend and I found this cool bug, where (since armour stands are entities) a wither will attack them instead of the player, unless you hit the wither.
A video can be found about the topic here: https://www.youtube.com/watch?v=Awp_8Mk ... _QlLVyyy1w

I think it's a cool little bug, and I hope it's not fixed.

Imagine all the Minigame opportunities if this is not patched, maybe a wither chase?
