It worked before so what could be the problem.

I just need a little help.

Everything works fine but when i enter a vehicle from flans mod my game crashes. I have allocated 12GB of ram. so i dont know what is the problem. Error: java.lang.IndexOutOfBoundsException: 508

And also you dont have to install java manually just install minecraft.deb and it works because java installs automaticly if you install it with gdebi package manager or the software center for kubuntu

Oops installed java the wrong way

Wenever i want to start forge on kubuntu it crashes (T_T) launcher_log.txt latest.log

i installed the nvidia driver that i need every game i have on the Computer runs better what am i saying EVERYTHING runs better but minecraft does still not work

its not here

yes it is

i gues
