Alright, try this now. When you clicked export, it gives you a series of things that were exported. I recommend you write each one of them so it'll be easier to get to. Next, go to the exports in the FeralHeart folder and search up every item that was exported in there. Move the map file into a new zipped folder and drag every other item in there. Upload it to mediafire and give the link to someone and see if they see the portal.
