Is this some kind of joke?... After restarting, the server did not boot at all, I checked everything, including the logs, and found only this error, listed below. I unloaded the plugin, and lo and behold, the server started, but with the map completely reset.... The players sent a damn server. Thank you very much for your attentive work..

I double-checked 6 times-this particular plugin was causing the problem.
