Can saves be made compatible with SB3?

I’ve learned recently that save games break any space build entities that you had spawned. Is there any way to make it so saves do not break the entities? I know I could use advanced dupe but I was wanting to slowly colonize all the planets on a map one buy one. Also will the atmosphere of a planet I have altered return to its original conditions when loading a game? If so any way to fix that?

you cant make them compatible with SB3, and dont use saves, they tend to break a lot.

shame to hear. Is there maybe some other way I could do what I want? Is there perhaps a way to save the state of a multilayer game?
