The llamas which spawn with wandering traders are completely invisible and the spawn egg of the trader llamas is also missing its texture. I am not using any texture packs or resource packs. This is reproduceable by going into the creative inventory and grabbing the trader llama spawn egg.
I'm not sure if this has already been reported, but I couldn't find this bug specifically on the tracker.
