The tactical battle map editor crashes the game when the "Blank map" checkbox is not checked brefore generating a new map. Otherwise it seems to be buggy, too, the empty map is unmanageable.

Edit: I often get a crash in strategy map editor, too. It is randomly and I get it by generating or loading a map into editor. I get it more often when I navigate to main menu from editor and then back to the editor and generating a new map.

However the tactical battle editor always crashes.
