Invisible Wandering Trader

What I expected to happen was...:

Walking casually through the biomes during the night.

What actually happened was...:

I saw a couple of random llama's on leads and they were connected to something invisible and moved very quickly. It doesn't work it click on the wander

 

Steps to Reproduce:

1. Walk casually or randomly through biomes.

2. See random Llama's run up to you with a leash.

3. Not rlly much you can do after that...
