Attached is a save showing the problem.
When moving the mouse over Lyons, you can't see what's inside. When deciding to attack the city, you can't see what's inside.
Using Hide Python Exception=0 settings, you can see a C++ exception is sent when mousing over the city. This means it's impossible to play the game when showing the python exception, and I later in the game had to send tanks agianst Moscow never knowing how many defenders there might be in the city, which was quite annoying.
