I usually have a limit on what Microdem can handle on my machine when it computes the map area size. Anything over 9000 pixels square just doesn't get computed ... which is a shame, but there you have it ...

And Zip_Alpen map is loadable in the game itself but almost invariably crashes when being used in game. I think it is about 16000 x 6000 pixels.
