I select an EnderDragon pet, then hide it. I die, respawn in the Lobby world, then use /back. Now theres a passive Enderdragon circling me, and /pet hide says i have no pet. It's called Ender Dragon, not Ender Dragon Pet. If i /pet show, i get a new pet pet called Ender Dragon Pet, but the original one is still circling me. If i disconnect and reconnect it's gone.

This should now be fixed. Thanks for reporting! 😄

What version of the plugin was this on? If it was 2.3.3, try one of the later development builds to see if I fixed it :)

Should be the development snapshot from yesterday.

Hmm. Try 410.

Same thing with build 410. Heres some junk that shows up in the log when i die.
