Minecraft Error: Java. Lang. Illegalargumentexception: Bound Must Be Positive, Unable to Play Single Player?

I host a personal server running mostly the same mods. The exception is a few Just Enough _____ mods for different mod packs. The game loads up and even plays in the server I host but I cannot run a single player world without this error. I tried making sense of the code, but to be honest, I cant read java. I know very very little. So its all gobbly gook to me. Anyone make sense of the crash report?
