Horses and Llamas have messed up textures.

Horses and Llamas, including trader llamas, have messed up textures. This started after the 1.19.20 update. Wild horses flicker wildly from their coat color to solid black ( which could possibly be a seizure risk in those with epilepsy ), and appear all white when armored. Llamas ( trader llamas ) appear red and green. 

 

You can recreate this issue by spawning a horse, llama, or trader llama in the newest update.
