Ok, so I've downloaded many items that I use in my maps, like derek, Hammy, and Items from may other users. All items appear correctly, and work in Map maker, and also test well. But Once I've exported the files they don't show up in FH (Once I go to the map through the Cape of Worlds). It's a tad bit frustrating (I'm honestly not sure if i've mentioned this problem before, I just know I still have no answer)
Could someone tell me why this is happening?
