When loading a world FML becomes corrupted

Recommended Posts

2013-05-19 22:39:58 [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.

When loading a world if there has been item id changes, it will prompt you asking if you still want to load, upon clicking on no, looking a tthe multimc console it reads the above, is there anyway to fix this without rebuilding the jar. Using Forge 689, even thought it says to use the latest (which do not work).

hm, there are a bunch of jar mods you have. Try without them and see if it works. Most likely a conflicting jar mod.

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.
