I already reported this bug on the Discord, i do it here for posterity.
Since scalable interface update, selecting a galaxy subsystem (nebula, cluster, star , planet etc) wich is in another galaxy will end up by a "object not found" result. Galaxy must have been loaded visually for the adress to be recognized. This was a rare issue in previous SE version, but now it happens 95% of the time (it will work with galaxy you have already wisited in the session).
Another illustration is that you can't load a save location which is in another galaxy.
