There's a bug in the game where there's a random UI freeze, but I can still hear the music and sounds. You can click and hear the music and sounds, but the UI won't change and will just stay the same.  It's game-breaking because I can't progress unless I let enemy ships attack my planets. I tried saving and autosaving, but none of them didn't work; you can't get around it. Everything freezes, but the mouse cursor, the music, and the sounds. I have this game on Steam and the game is to date with the updates.
