-> Using Connector in Youer:

Install the fixed version (opens in a new tab) of the mod.

The principle is that Connector modifies the BRIGADIER_MODULE location during startup, but Paper has already heavily modified brigadier, causing it to not be recognized correctly!

Connector may affect plugin communication, causing certain menu cross-server functions and cross-server PlaceholderAPI variables to not display properly. This is a known issue, please do not repeatedly report or guess the cause of the problem.
