Все, что могу сказать по той инфе, что ты предоставил, ошибка в данном участке кода

Код:

@Override
public void run() {
  for(String name : plugin.getArenas().keySet()) {
    plugin.getArenas().get(name).spawnMobs();
  }
}

Скорее всего, тут

Код:

plugin.getArenas().get(name).spawnMobs();

Учитесь читать ошибки, это не так сложно)
Ну или хотя бы вставляйте полные ошибки, а то вы предоставили только стек вызова. Ни типа ошибки, ни сообщения нет.

 

Еще не тестировали код на двух и более игроках?)
Напоритесь на ошибку в коде, а именно в MiniPlayer. Изменяете статик переменную в каждом инстансе объекта.

Так лень найти 14 строчку в классе RunMobSpawner и посмотреть какая переменная там null?
И код лучше под спойлер давать, можно и обернуть в

Код:

 

Я разобрался
