Feral Heart

Well, I made a map for my sister and I to explore, (either way, she can't access it in Mapmaker because it is apparently missing the Terrain.cfg file or whatever...) and when we got there, she said she couldn't see any objects. I thought it was because of the terrain error, but then she went into Watermill, and the lush map was barren. yet, when we ran through the other maps, she could see all of the objects there.

Does anyone know how to fix this missing object error, as well as the Terrain error
 (I've checked the help forum and did what it said to fix the terrain error, and yet it still didn't work. :/)
