Omnimatter.

Check other mods you got installed, I had a lot of mods installed but after I started updating, it gave a lot of issues regarding "pumpjack". Try and remove all other mods except omnimatter to verify if it is the omnimatter mod that is causing the issue :)

Ah, there we have it. Doing troubleshooting and with bobs it loads, with Yuoki it doesn't.

Oh yeah, I forgot I tested this a while back, Yuoki is incompatible with this mod atm

It is attempting to remove everything related to pumpjacks so if you got anything that uses them that causes issues please tell me.

Not sure what part of Yuoki uses pumpjacks but your removal script goes crazy when yuoki is installed. And,,, I still don't have the "lost" pure recipes returned... Meaning that I'm lacking the Omnic acid 1-4 and others. Almost at the point where I'm considering starting a new world as your mod was the biggest reason I started a new world in the first place :P
