Установил плагин UltimateClans V.6, все пункты работали, ошибок никаких не было, пока я не решил сделать сам клан. По какой-то причине, он, формально, создается, но при этом не сохраняется в базе данных. Вот такую ошибку выдает при использовании команды /clan create:

Кто знает, в чем проблема? Я использовал и MySQL базу данных, и просто yml в самом плагине, ничего не работает, после перезагрузки клан пропадает, и забавно, что написано upload users: 1, а upload clans: 0. То есть он запоминает игроков, а клан нет. Ядро purpur 1.19.4
