Bob's Ores still seem to generate and ignore RSO. I've tried default settings, modified settings, and everything else I can think of. It's come down to disabling every other mod, so my entire mod list is simply: bobores-0.16.1, boblibrary-0.16.1, bobmetals-0.16.0, and rso-3.5.2 (factorio-0.16.15) - no updates are available for any of these. The ores even show up on the Preview screen unlike vanilla ores.

Edit: Seems like it may be load-order related? I added /"? bobores >= 0.16.1"/ to the rso info.json dependencies (it was empty, idk if that's intended) and it seems to work perfectly now.

Got the same problem, while I was searching my map, a lot of resources appeared.
My settings was to very low frequency. The save is a mess now.

I cleaned up dependency list since I was pretty sure it was not needed anymore.. I guess I was wrong.
I'll add it back and release new version.
