Hi there i just added your plugin and testing it out and i notice that when you mount pets then set the mounted pets name it will not save. I'm using mysql so i can link the plugin to another server. I also tested with a wolf and creeper, but also happens on any others i test.

Also i use spigot with bungee and i have had a few rare issues with the mounted pet duplicating and once you switch servers and come back that pet is stuck on the server until restart but if you leave on the server you spawned the pet and come back it is perfectly fine.

If you need any other info let me know more than glad to help fix this tiny issue.

EDIT: Just switched from my hub server to the creative server where i have the plugin also installed then went back to the hub and now i have a creeper on the wolf like its suppose to be then two other pet creepers following me...

What version are you using?

For the plugin? It would be the newest version from bukkit
