While briefly and casually using the editor the game is crashing quite easily... the editor feels very Beta_2_ish.
Also when a road crosses over a river it should automatically create a bridge. I'm also not discovering how to edit things which have been placed on the map. Right-Clicking on anything in the map editor should bring up the editable properties of anything and everything in that specific square.
