Heh.. just had a funny moment with the sim.

Somehow I had two tabs of the simulator open and logged out in one of them. 30 mins later I re-discovered the other tab and clicked on throne which got me into an empty province with all values zero and multiple "division by zero" errors.

Not a problem by any means just wanted to mention it. If you want to be perfectionist about it some kind "session expired" message and/or redirect to login would probably look smarter. :)

Can also be recreated by just browsing to /simulator/sim/throne.php without logging in first.
