So Wyrmsbane recently bought Silver, and asked about spawning pets.
I wanted to be sure that the pets worked in the first place.
I was in creative at the time, and the command didn't work, even when attempting to spawn a simple pet such as a chicken.
I went to the survival spawn, tried the same thing, and that didn't work. I tried /rtp and teleported to the middle of nowhere, tried again, and nothing.
I don't know if this is intentional, so I'm making this just to be safe.
I get the error "You have selected the ___ Pet" followed by "Pets are not allowed to be spawned in this region."
I would've uploaded a screenshot but it's not letting me. nice (sorry).
