So, I'm trying to play a modded survival series but the NEI interface will disappear once I go past page 15 pf 28.  I'm not toggling it with "O" and I don't know why it's doing this. Also, on page 5, the lower 3/4 of the page has texture-less blocks which are all white and the page number, next & prev buttons, and item subsets all go white as well.

Here is a list of the mods I'm using:

Damage Indicators 2.9.1.6

cofhcore 2.0.0.2

InventoryTweaks 1.56-b77

Morph mod beta-0.7.0

OptiFine

powercrystalcore 1.1.8-9

projectredbase 4.2.2.19

projectredcompat 4.2.2.19

projectredmechanical 4.2.2.19

Tinker's Construct 1.5.3

Thermal Expansion 3.0.0.2

ZansMinimap

 

Nevermind, I figured it out, OptiFine wasn't compatible with the orespawn mod.
