Other information

Running modpack version 1.3

does it happen with just the thermal mods + patchouli?

I believe the root cause here is optional pages, from what we can tell.

If you have ALL of the Thermal mods, this won't happen. If you have different modules which provide alternative methods for acquiring items, then this apparently can happen.
