Imma just get down to the point...
1]] Go to your C:\Feralheart\Media\Terrains folder.
2]] In that folder, you should find the folder 'temp.'
3]] Open the folder 'temp' and click on 'tempObjects'.
4]] Press CTRL-A and then press Delete.
5]] Hover your cursor over the buttom 'File' and click 'Save.' DO NOT CLICK 'SAVE AS.'.
6]] If you have water / gates in the map, do the same with the tempWater and tempGates.
7]]Open FH, load the map, and click 'Test'.
8]] Exit out and see if any objects appear.
It worked for me; I don't know what happens to others. o3o
