That was it, thanks R0J0hound. I sized the minimap off of the viewable area, and didn't think about sizing it based on the layout size.
I've had another problem with the minimap Plot Object color is getting lost on some layout, while working fine on others.
Some images to explain the problem. The event sheet is shown at the bottom of the images.
The Objects (player and two other sprites) are being colored black:
They should be the color of the sprites instead (it works on other layout with the same events):
This is the Event sheet that both of them call (with minimap stuff circles)
On the first screenshot if I remove the minimap events for drawing terrain it will plot the colors the intended way.
