I think I am having a similar problem to what infinite_monkey is describing above me. Although I am having it with the advanced particle collector instead of the karbonite converters. I'm not getting any of the special buttons needed to open karbonite/karborundum collection on the APC. I've checked the config files for the part itself, but I didn't see anything that was obviously out of place.
I've been flying out to the karborundum band, save editing, and then flying back. So I'm not really hurting for Karborundum, but I reckon it might be a bug since it seems to be in the same vein as what infinite_monkey described.
And lastly, your mod-suite is nothing short of amazing. I can't imagine playing KSP without the MKS mods these days. Thanks for allowing me to live out my Elon Musk e-cosplaying fetish. Duna will be mine!
