You can reinstall without having to redownload the entire game by:
1) cut/pasting the contents of C:\Windows\Users\{you}\Epic Games\SatisfactoryEarlyAccess anywhere else
2) uninstalling the game
3) installing the game again, but pausing the download once you start getting some data
4) cut & paste that folder back to where it was before
5) resume the download, it'll take just a couple minutes
don't worry about your saved games, they won't get deleted
confirmed this works & fixes the bug :)
