Optifine Crash?

[Kiraaa]

Ok so whenever I start singeplayer world or just go on one Feed the Beast crashes. When I disable optifine it starts to work again. Multiplayer works fine.

you need to use an updated version of optifine, aaaaand an updated forge too.

Use Forge 518 and Optifine 1.4.7 C3
works perfectly for me
