Bug: Abadan Peninsula Black Screen - Bug

[Mobhack]

Confirmed - saving the map in the scenario editor looks like it fixed the (presumed) bad data.

- enter scenario editor, immediately select custom map, load map #40
- now select edit map
- in the map editor, press M to turn map text OFF
- then press M to turn it back ON again
- now save map to same slot with same name
- exit game, then restart (just to be sure all is cleared down)
- enter scenario editor, select map 40 as the custom map
- purchase troops and proceed to deployment phase
- no black screen from panning map this time!
