[SOLVED][MC 1.7.2]Crash on EntityPlayer.openGui()


Recommended Posts

Hello Guys!


I got an NullPointerException on opening my custom gui. I already debugged my mod in eclipse, and what I found out is, that the Exception was thrown from NetworkRegistry.getLocalGuiContainer(). Further I realised, that my ModContainer is null. Can it be an internal error?
