[1.3.3][SSP] Crash with latest Forge

In an attempt to upgrade my other mods I am required to update forge. This appears to break ComputerCraft. The game loads fine but receives Saving Chunks when loading or creating a world.

The error is as follows:

Minecraft Forge 3.3.8.152
FML v2.2.78.153

It doesn't seem to be a ComputerCraft error. I have the latest forge and CC runs fine. Try reinstalling forge, and see if it works without mods, then add CC and test again.

If I load without CC folder, world loads fine. If I load with CC folder, I get that error. However I'm following a lead that it could be caused by Optifine. Testing that now.

Yep it was Optifine. Upgraded to C3 and the error no longer occurs
