I have the problem that when I join the server, my Minecraft sometimes crashes.
Even if I join one of my worlds. Have the problem only recently, and did not have it before.
We need a crash report else we cannot help you
If I click on "Show Crash Report" nothing happens, and I will not see it either, only if I go to "More Information" :
The game crashed whilst unexpected error
Error: java.lang.NullPointerException: Unexpected error
It's there everytime
Re-download the mod, you're running a unpatched version.
Ok, thanks
