I just ran into an issue, not sure if it's OPM or Kopernicus related, but I *think* it is, so I figure i'll drop it in here.
I noticed after I installed bleeding edge release 9 and OPM (was running stock solar system before that), that I stopped getting asteroid spawns. There were a few in orbit of Sarnus, but that's all I could find, and my SENTINEL scope in orbit below Kerbin wasn't finding anything either.
Checked the console after warping a while in the tracking station and there's a ton of NRE spam in the console. I backed up my save and pulled Kopernicus, MFI, and OPM out, and fired KSP up and went into the tracking station, fired up time warp, and pretty much immediately a bunch of new unknown objects spawned in around Kerbin, and there's no more NREs in the console.
