When I went to join my friend's world to check out the Warden together, I noticed that the Warden Spawn Egg and the Warden itself does not have a texture.

Expected Results
Both the Warden and its Spawn Egg have textures.

Observed Results
Neither the Warden nor its Spawn Egg have textures. The Warden also does not play the sound it makes when summoned from a Sculk Shrieker, or when it digs back into the ground.

No Global Resources or Resource Packs are active.
