Broken cosmetic floating in world

[sakyrah]

Describe the bug

Have switched hosts, uninstalled the plugin, updated game versions to 1.21.8, and this floating hat cosmetic remains eternal. I have no idea why it's there or when it happened but it just appeared one day and we can't get it to go away, even with entity kill and modification commands.

How to reproduce

I have no idea. More than likely this has something to do with the fact that the models themselves aren't being handled properly. They don't get purged upon uninstall, you have to go around and break them all, or they become unbreakable and stay forever. Take a page out of Nexo's book and figure out how to implement that, and that'd probably fix this issue? Why a cosmetic would be stuck is even more mystifying - I assume it has something to do with a restart, but I don't know.

I haven't used this plugin in months.

I am having the same Issue. I added a backpack to my character.
After deleting the model.yml from the models folder, the backpack was still where i was standing.
It is not removable at all.

The same thing happens to me, but with the hat.

Also, when I break an item to move it, I get this error.
