Вылетает майнкрафт при заходе игрока на сервер

В общем захотел поиграть в майн с другом, мы установили одинаковые моды, одинаковые версии, я нашёл идеальное место для дома и телепортировал друга. После чего майн вылетел (при чём у нас обоих).
Потом я опять создал сервер, друг пытается зайти, но у меня вылетает.
