Paper is a high performance fork of SpigotMC and as per their documentation should be backward compatible with Spigot plugins. Unfortunately while the MCLink correctly detects the authorization of the player, it fails to kick them out. I understand that I cannot expect support for all forks, but Paper is one of the most common ones used. https://papermc.io/

I would love to and have tried to make thing work, but I do not understand why it doesn't. I don't have much experiance with paper, so if you do and can help me, that would be graet.
