I think your best solution is to set FH back to default without modifications. Then try downloading your markings and items.
FeralHeart Default Folder & Separate Files 4 u!
First of all, if you're wanting the Default Feral-Heart Folder (which includes EVERYTHING that is in the DEFAULT Feral-Heart folder which comes with the game after installing) then download it here. If you want separate folders then keep reading on!

Replace what you want with the current files/folders you have. Example: I want to replace a current fur texture with the default one, so I place the default fur texture with the one I have in my texture folder already. I then replace it when asked. Do this with the other things you want to replace with the default FeralHeart goodies.
