Thank you.

Implying a single word will help me solve my problem. At least, mind providing a link?

I have edited the class WorldServer (jr.class) and am trying to replace the current one in the Minecraft.jar file. In the vanilla version I can do this easily, by removing the META-INF, but Forge crashes. So how do you edit Minecraft base/core files without having Forge go hardcore paranoid?
