The following textures show up with the pink and black missing texture icon in JEI and is possibly due to not following the all lowercase file name rule implemented in Minecraft 1.11. Also this appears to cause crashes when using Optifine.

-Control Circuit (also note that control is missing a capitalized C in the JEI when hovering the cursor over it)
-Sensor Module (also missing capitalized S in sensor when hovering the cursor over it)
-Redstone Control Module

Oops, looks like i missed a few things when renaming stuff. Should be fixed in next build, thanks for the report.
