I have now fixed the 2D maps. The old software that I was using was not supporting the 1.2.4 file format. So what I did is finally write a program that assembles all images from the flat 3D map into one picture… a bit around the corner but the advantage is that we depend on one less software now, achieving the same.
The display of the Worldguard regions in the 3D maps is now also OFF by default. You can still switch it on in the layer menu of the map however.
While the 3D map updates instantly. the 2D map will be created from the 3D map only once a day.
