For the NEI bug, go to your FTB install directory, go to mindcrack, then minecraft, then locate the saves folder. Open it up, and delete both the NEI folder and the NEI.dat. Then, go into the save where this started off and delete the NEI and NEI.dat which is in there again. This will reset all your NEI settings, but nothing too much actually happens unless you have lots of configuration in NEI, which almost no people have.so even un-changed ultimate 1.0.2 (except adding liquidXP and CJB API + CJB Quickcraft/moreinfo) it crashes
I'm not going to bother with that and am just gonna downgrade.
