My apologies if this goes against the rules as i am using a modded version of Direwolf20's 1.6 pack. I have removed Applied Energisics, Billund, Compact Solars, Computer Craft, IC2, Logistics pipes, MFFS, Modular Power Suits, Open Peripheral, and Q craft. I have changes the universal electricity config to not load the IC2 module, and disabled the IC2 portion of Railcraft. Whenever I look in NEI to see the uses of an item my world unloads and does not leave a crash report. Recipe lookup works just fine, and in all other respects everything works normally. I have looked into the config for NEI and NEI addons, but I don't see anything that appears to be the problem. I Also did a quick search of the forums but didn't see anything resembling my problem, my apologies if i missed something.
