There was a terror mission in Vienna (and looking at the map it's indeed in Austria), a message popped up mentioning that the terror mission was in Vienna, Britain.
Consecutively, the mission map loaded was Britain, the one with the telephone cells and postal boxes.
Sorry, I don't have a ufoconsole.log as my pc crashed shortly afterwards - not related to the game. This should be easy to fix though, it must be in the decision point which map is loaded when.
