Help with multiverse-inventories

Hi aternos team, today i did the request to add multiverse-inventories plugin for 1.16. You answer was "already added" but If I put it on my 1.16 PaperMC server it not works and give problem in log, like "try to delete it" and "try to install another version"

You avn't added it or is a bug

Sorry for my english but i'm Italian,

Please try to fix it and tell me if you have success!!

Thank and goodbye!!

And what i can do, i need to separate this inventories, i cant remove multiverse core

When can appen this?

because there is multiverse core for 1.16 bit non multiverse inventories!!
