It appears that the world you were playing on unfortunately crashed rather than us manually rolling back the server.
I know it doesn't do anything for your situation, and I am really sad to see this, but if you got the pet just before that happened, it wouldn't have registered as you actually getting the pet :(
If I could get a kiss/crying emote next to me in game we would be square no cap
Meet me at the G.E, you pick the world. I'll be on my personal account but it's the least I can do.
