UE5.1 won't save due to "linked to external private object"

So doing some C4D tracker > UE sequencer, and for whatever reason UE hates the Datasmith information for the camera solver it brings in and refuses to save. Keeps pointing to the MovieScene_0.CineCameraActor_0.CameraComponent despite all relevant actors being deleted, and says “(referenced because it is an archetype object)”.:

Ironically the only way to save the level is to delete the literal camera solver cine actor with my tracking data lol, putting me back to nowhere.

Answering my own post again, seems to have something to do with converting camera to “spawnable” or “possesable” in order to get MRQ to look at camera correctly that sometimes doesn’t happen on render.
