Relic Castle

So I went to Gimp to make a fog for my game. I took a screenshot of the map,paste into Gimp,crop out the useless parts.
Then I was left with the map only(with black border in Inside map).

I draw the fog in a new layer,so that It looks like there is something going on the TV in the house

But when I import in into the game the fog gets misplaced like in the picture below

Does anyone know where did I do wrong?
