Whoops. You are correct. NEI's forum front page isn't updated so I didn't even think to look at MC version number on the download page. Something about your problem sticks in my mind relating to NEI though. Reminds me of NEI lag issues. Turning off synchronized search with AE terminals and making sure no subsets were hidden in NEI was the solution...but I'm certain this was fixed as I was able to do both in an updated version of ImpactFlux.
That wasn't solve the problem either. I know you're trying to help and thank you so much, but that really annoys me sooo much. I LOVE this pack but it's currently unplayable to me
