Pretty sure this is why I'm crashing, don't know what it means though.

Hey, just wanted to say that I get the exact same error since installing FTB Unleashed, only in Jungle Biomes though. Any ideas?


EDIT:
Aaaaand solved. Somehow Optifine's connected textures cause those crashes for me. Without connected textures, everything works fine! Hope it helps.

Thank you for your reply, I have been searching for a fix and no one seemed to figure out what was causing it, but as you stated, turning off connected textures worked perfectly... it's weird that it only made it crash in jungle biomes...

Thank you. +1 for Optifine's connected textures around a jungle biome causing a crash. turning it off allowed me to explore the jungle and one far enough way I can reenable w/out crashing.
