it was enough to rename nicknames when the player is offline. which was the problem.

there were errors when the player entered. the plugin seemed to work. I don't know exactly. then the problems started. some nicknames began to return to the original name. as a result, I returned the old version. I didn't even understand. There may have been a problem in the data file. Don't know. The old version of forever.

If you're having an issue with the newer version, feel free to provide details. The error I assume you had was already fixed in a hotfix, otherwise all changes made are mentioned in the changelog.
