When you add the maproom to an Airfield it will default to the center of the runway:mad:
The way I fix this is to select the move option and drag the maproom off the runway into the grassy area to the right of center;)
When you finish the drag, it will look as if the maproom snaps back to the center of the runway.
This is because there are 2 parts to a Maproom,
The visable part stays where you dragged it and the invisable part snaps back to the center.
When you are in the game only the visable part will be seen, right where you put it:aok
