[Self-Solved] What is this extremely weird output error supposed to mean???

[Gaara51]

Last night after changing some ID's in my mod, I randomly started to get this error whenever I traveled to my dimension.

2013-05-02 16:29:39 [sEVERE] [ForgeModLoader] The ForgeModLoader state engine has become corrupted. Probably, a state was missed by and invalid modification to a base classForgeModLoader depends on. This is a critical error and not recoverable. Investigate any modifications to base classes outside ofForgeModLoader, especially Optifine, to see if there are fixes available.

In it says that is not recoverable, and I edited base classes. I never edited any base classes and in fact backed up my source files, and completely made a new entire forge, mcp folder. I still get that error though. (I also changed the ID's back to their original numbers.)

 

It had to do with my ChunkProvider, and Biome. I have it all fixed, thanks for any one who read it.
