Mine did that also, when I downloaded it on my surface tablet. No idea why. Haven't tried it since I downloaded though so can't tell if its still like that.I feel dumb for bringing this up but I downloaded the pack and NEI is STUCK on cheat mode. I can't seem to turn it off. Also when I spawn in, I'm immediately in creative mode. Changing to survival does not fix the cheat problem...nor does going into NEI.
