after a few games on the map "Harbours", that I think is was buged, I have decided that I will do my map with similar proportions 10x20, vertical map. When i started it i saw something like this:

"world borders" ignore height, and only fit to maps width. I tested other 10 vertical maps from vault and all have this problem.
Any ideas how to fix it? I think the only way is to make map from the begining with horizontal proportions :/
