Крашнули книгой

 

два раза такое произошло, не уверен, что книга

Если всё-таки книга, как от такого защититься?

 

Спасибо за совет, попробую этот плагин[DOUBLEPOST=1492935393,1492922989][/DOUBLEPOST]в PacketsBookFix ничего настраивать не надо, кроме числа пакетов в конфиге?

 

а где взять последнюю версию ядра ?

 

Можно вообще ничего не менять, там и так все отлично работает.
MaxPackets это на 1 игрока .Аднёрку ставь и не парься.
