I've been searching for an answer on this for a while.
I have no problem getting the overhead map to show up in map selection when you are starting a skirmish. The overhead map that I saved and then edited to place the starting points displays correctly during map selection for a skirmish.
When I tested the map online with a friend the display showed a bright pink box instead of the overhead map.
Is there anything I can do to get that overhead map to display properly in multiplayer map selection?
Is this due to file format options when I saved the .tga?
