NVM - I posted the same questions on Steam and it turns out I needed to verify game integrity.
A week or so ago, not really sure, but it updated and when selecting an object you could turn it into a black hole with a button near the light pulse/ destroy planet buttons.
Well, for some reason it's gone now.
Also, every time I start the software, Steam asks if it can make changes to the computer (I guess this is an update), but it never does...
The following has nothing to do with Universe Sandbox, but I haven't been able to play Portal 2 for some days either. (Steam)
