Log contains all information needed

i already have the suppsoetion that it is the Cubic Chunks mod since it is the only mod i normally don't use, all of the other mods are more common and work fine with IE in other packs

Use the search function and downgrade Forge.

i didn't know what to search for

also if i downgreade forge some other mods like AE2 won't work anymore becuase they require the newest version

hope this gets fixed in a future release
