When things like this happen your best bet to get things back to normal is usually to just reinstall the game into another location of your computer and drag and drop the files you replaced, lost, or possibly damaged into your FH folder to replace them... however if that doesn't help still you might have to just uninstall your game and delete the Feral Heart folder and then reinstall. (If you go with that last option be sure to back up all of your important files like presets, maps, and screenshots etc.)It's nothing terrible that would require those measures; I happen to have backup files. Thanks anyways.
