Windows .exe Direwolf20 cannot load maps

[SpartanBlockhead]

The Direwolf20 modpack just updated to 1.4.7 today. Yesterday it was working fine as 1.4.6, but now it just says "Building Terrain" forever when trying to load a map. I have added LogisticsPipes and Optifine to the modpack, both are updated to 1.4.7 (Optifine says 1.4.6 in-game but the download at minecraftdl says 1.4.7). The console gives these error messages:

Any help with this?

UPDATE: It works fine after disabling Optifine, but I really want to keep it. How can I get past this error?

from what i understand, the only version of optifine that currently works with the version of forge installed in the v5.0.1 is Optifine C1 which is experimental and very unsatble. is messing with block updates. REALLY BAD. probably easier to keep using v4 until new/better optifine is out

Optifine c2 has been released like 2 hours ago, and is supposed to fix those issues. It still is a preview though

 

[Thethhron]

Hurray!

 

[SpartanBlockhead]

Why was Optifine working perfectly before the 1.4.7 update though?

since Optifine was for 1.4.6, the C2 one can handle the new Forge (1.4.7)
