JD I fixed it, since those were the only two addons I had recently added I just made a hunch and removed the addon that was inside a cluster (Nightfall), that reset the star cluster 47 Tucanae back to normal and I have my black hole binary system back again - with the same planets as before
Also as a note- using the 5M pak of Gaia causes flickering of textures of exoplanets if the LOD is set at 1, so I put LOD back at zero and that went away. Also I was told to set AA to 32x, but that causes 100% graphics usage so I put it back to my original setting of 4x. That reduced GPU usage to 60% and it was further reduced to 35% when I set the fps limit to 30 fps. I also tried 15 fps but that only got me down to 25% and also caused texture loading delays so 30 fps seems fine with the above settings.
Going to add two of the planets I was looking at with the above settings, seeing the sky of a planet inside a star cluster is amazing!
