It worked!
Installing SVE 1.2.4.1 instead of 1.2.5 and using my eclipse cfg's has made the eclipses appear on all planets! Some things are changed though, sunflares are more or less gone and Tekto is a bit darker, but hey, that's fine. The fact that Hale and Ovok were light while Sarnus covered the entire sky in front of the sun just bothered me so much. Thanks for helping, Galileo.
EDIT: I've done more testing to see what else is different. Lens flares can be added back by adding Galileo's Sunflares, but the flare covering the sun was not fixed. While Tekto is generally slightly darker map view and the Tracking station, the clouds are a solid layer the same color as the highest clouds while playing in orbit. Everything is normal again once in the atmosphere and everything is normal at the other planets, also. I guess I'll just wait for the next update of OPMVO and everything will be perfect.
