posiadam 2.0 wersje spolszczam InClassTrans i mam już spolszczone ale jak klikam w Gui party to nic się nie dzieje + no i ten error jak nie spolszcze to to normalnie działa lecz nie robie żadnego błędu bo nawet jak zmienię jedną literę to się zmieni ale automatycznie nie działa wersja serwera od 1.8 do 1.10 a Sky wars 1.8 do 1.9

silnik 1.8.8
