hey -MM-, first of all, I love your mod. I use it all the time. But I have a question. I've recently installed a new set of mods and it seems that your mod is not working nicely with probes plus. Install both KRnD and Probes plus and almost no parts can be modified by KRnD. I've noticed that probes plus uses some sort of upgrades in the tech-tree and I have a feeling that's responsible, but it doesn't explain why a few parts remain modifieable.
Anyway, thanks for your nice mod. keep up the good work.
