KaiserRedGamer you can try to restore a previous save from your file manager.
For this, go into your game directory (see path on screenshot if needed), then navigate to Saving/Worlds:
This is the place where your worlds are saved.
Then go into the concerned world's directory. The content should look like this:
The Persistent folder (in green) contains the world in its current state. This is what the game tries to load when you click "Resume game". Under the "Quicksaves" folder (underlined in blye) are all your quicksaves.
To fix your issue, I recommend to:
- move the content of the Persistent folder into another temporary directory (so that you can revert your changes if you mess up with something)
- copy the content of one of your quicksaves (preferably a recent one) into your Persistent folder
- restart the game and resume the game.
This should restore your game to a previous state. Your asteroid will be lost however.
