Logging out on a mount makes an unkillable ghost Pokemon

[Amerith]

At first it seemed to only happen while create was present but I've since been able to do this without it after further accidental testing.

The only mods present are Cobblemon, Cobblemounts, Create, and their dependencies

Steps to reproduce.

1. Mount a pokemon.
2. Close world
3. Close game
4. Restart game
5. Open world

Result: A duplicate of the Pokemon you were riding with no AI that is immortal/unhittable
Closing and reentering the world again gets rid of the ghost.

A video has been provided below as proof.

Video has been edited to cut down on in game loading time in footage.

I swear I'd opened an issue for this, this has been a thing since 1.0. You actually don't even need to close the game for it.

Issue also present in multiplayer. Fixed by restarting the server.
