So, here's the story.
My Feralheart was working fine. I had the Pawesome Items Pack and the Mass Markings installed and working great, everything was showing up. But then I downloaded a mod that sort of screwed up the lighting in the game, and long story short, I had to get rid of all my Feralheart files and redownload it again.
So then I download the two original packs I had, Pawesome Items and Mass Markings. Pawesome Items worked fine, but for some strange reason, Mass Markings wasn't showing up, despite the fact I put all of the markings in the right folder?
Maybe I did mess up something? I have no clue. I haven't attempted redownloading Feralheart again yet, but I will I guess? Stick around.
