I am getting the same errors!! It totally screwed up our FTB world/quarry and my NEI invo pages. UGH!! it happened after the FTB update the other day too. I tried fresh install and everything. Don't quite know what to do
I just encountered this issue myself... Im not entirely sure what the root cause is but I guess it is due to corrupted mod and/or config files. Personally, I am using the FTB launcher in order to obtain the Direwolf20 mod pack. Initially I tried a force update using the launcher after deleting the mod folder... However this was not enough as the error remained.
The solution was to backup my saves folder (and options.txt) and delete the entire minecraft folder (except launcher). I then forced update once more and obtained a 100% clean installation. I then placed back my saves folder and options.txt.
Just to be sure, I also deleted the NEI.dat and NEI folder that reside in the saves folder. I am not entirely sure, but I think these two items may be the root problem.
After this your world should load fine once again, with NEI functioning properly. You will have to reset your quarrys (break them, place landmarks, place quarry) as their state seems corrupted.
I'm having a similar problem except it occurs when forge is loading. It go's until it says minecraft validated, launching. It then just stops. The mods I have are ferullos gun mod, shurtugal, thaumcraft 3, metallurgy 3, rei's minimap, eight bit pack, and twilight forest. I know I installed everything correctly. I've force updated and even deleted my .minecraft folder yet nothing works and when I delete the nei folder it still wont work and I cant find the nei.dat. I really need the mod since I cant remember every recipe so can you please help me. There's no files in my saves folder.
