What version of Opti should be used? Something breaks when I try to play SSP with Opti installed (the latest version)...
Here's where the Error Happens:
2013-03-05 15:47:40 [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.
