[Bug] Restoring backup breaks ability to create compressed save archive

[Terrorforge]

The game lets you create trimmed, compressed .tar.gz "save archives" from your saves for bug reporting purposes. These are saved to your save folder, which works just fine with Catapult:

However, if you create a backup when you have one of these archives in your save folder, it will not be saved correctly. When you restore the backup, instead of the archive, you get an empty folder with the same name as the archive:

This breaks the "create minimized save archive" feature for the world in question. I guess it gets confused by the existence of a non-file with the name and can't create a new .tar.gz

If it's not possible to just save and restore the .tar.gz, it should be deleted entirely to prevent this problem.
