During my multiplayer game on Minecraft Switch a peddler appeared but his llamas no longer had any textures. So I asked my friend if he saw the same thing. He assured me to see the same things.

I reconnected a day later and this time (I don't have a screenshot) the texture of the mounts had changed again this time it flashes. And my friend told me to see the same thing.
