Can't play with my custom systems

When I try to play with my custom systems, the planets don't appear to me. Game starts but screen remains black, showing only the UI.

Actually, this is hapenning with all games now... I can't play anything.

When planet generation finished and you see black screen try to press F5. Most likely it's will work then.

It works! Thank you!

If u don't want to do that every time there is a mod that fixes it
