Btw, I almost forgot about it cause at first I couldn't figure how to work it, then realized that you put all the files from FeralHeart/media/terrains. But when I tried entering your map, FH crashed -_-
I managed to load it in map-maker though and saw the fhCapeOfWorlds portal was outside the map and you had two completely useless custom portals in that same corner. I fixed it though by deleting the custom portals and moved the Cape portal to a location inside the map.
Btw, what is the Peradiceterrain.png, PeradiceMask.png and CliffRiverTerrain.png files for? I thought they were for the map, but you used the Watermill Terrain and Mask...
Just thought I'd let you know, I know this is an old-ish thread XD
