Why won't MindCrack worlds load?

[advorange]

It was working before the update, then I updated. I pick my world and then the screen just freezes at "Loading World Building Terrain". I logged off in the End when I last played. Why is this happening?

This is the problem (I think):

Nevermind, it was just Optifine B6. Saw that it was a problem for others.

Can you help me by sharing out how you fixed your problem because i got exactly the same issue. I've tryed to instal Optifine B6: standar, light, HD ULTRA.. all 3 one by one and i still get the same error. I can't create a land on singleplayer

Don't, I repeat, don't use optifine B6. Use optifine D3, and make sure you update your forge to at least #518 (the version used in the latest updates of the modpacks is #515).

Edit: Unless you are playing on a server of course, in that case, do not update forge!
