Thanks for the reply. I didn't do extensive checking of many recipes but I noticed that the Biolab output from the reverse factory is giving the vanilla output of 2 capture bot rockets, while the modded Biolab recipe swaps those for 2 Biochambers. The other ingredients are vanilla and so the reverse factory output is correct otherwise. I assumed a mod incompatibility where this mod is giving normal vanilla output and is not matching the modded recipe for that item.
Yeah, I was having trouble finding recipes that had been modified by Space is Fake to begin with; looks like they are indeed modifying certain recipes during final-fixes (not sure why, that's pretty bad practice, from what I know)
Fixed in v9.1.5 by adding it as an optional dependency, forcing its recipe modifications to load first
