Could you add a setting that will make it so that recipes that allow productivity won't be considered when creating the revere recipes? This way you can disable the dupe where you feed an assembler with productivity into a reverse factory and back again.

Hmm... productivity modules only affect intermediate products, right? That actually could work to prevent that little exploit. And as a setting, it would remain available to those who would desire such an exploit. While keeping the primary purpose of the mod intact. Sounds pretty good, I'll definitely get to work on that.

EDIT: Should be implemented as of v6.0.6, thanks for the suggestion!
