You may be missing your terrain.cfg in it's folder. The only suggestion I can give is remaking it sadly, or at least check in Local Disk (C:)>Feralheart>media>terrains>Home (if that's the map name, right?) and checking for anything that looks like terrain.cfg
If you find nothing like that then I'd suggest remaking it then, yes, and if you need object recovery then just put the other .cfg's I guess in another folder some where then remaking it, copying them then and replacing them into the same folder that was your map's folder where I told you to look.
Hope this made sense and well, helped. It's the only thing I can think of for now.
