Description of the issue:

Error logging into the server, the server reports that it lacks some items in the world.
without this addon, the error disappears. The world was re-created, configs are synchronized.
Perhaps the problem is not in this addon, but I can not understand what causes the problem, please help to solve.

It's not error. It's warning.
