I don't know when or how to fix it with our versions, but I swapped Kopernicus versions, grab the one in OPM and use that instead. It fixed everything. As for how to make the planet Oblate, you really can't without major heightmap editing, something I'm not fully capable of, or a PQS mod that I don't believe exists. Also, I did some testing by moving Laythe around Mysterio, Laythe's SOI is too large. I need to enlarge Mysterio again. Apologies. This time, I might actually need to move it.
