Hello,

 

I am very new to the Modding area. I wrote a Mod which gives me a cape on a special Server. Now everytime I connect my Minecraft crashes with the following Crash report:

I did not make any new class. I just edited some classes like:

 

EntityPlayerSP

EntityOtherPlayerMP

GuiingameMenu

GuiConnecting

GuiScreen

NetClientHandler

GuiMainMenu

Do not edit base classes, we do not support anyone who edits base classes.

Even for something so retardedly trivial as this, which can be done completely without any base edits at all.
