ЧТО ЭТО?! Сделал лаунчер Империя от Ленина все норм но при заходе на сервер выдает вот ЭТО!
Помогите в чем дело? Ставил моды, зашел в игру все норм одиночка работает, создал сервер, запустил (с этими модами), серв норм пашет, но при заходе на него выводит это. Удалил все моды с клиента и сервера, удалил почти все оставив основные файлы. Зашел в клиент, вкл сервер, при заходе опять выдает такую херь, причем уже без модов, то есть моды на это не влияет. Помогите кто знает в чем проблема?
