In two seperate occasions.
I am playing 1.01i (as SP) and Great Britain has, in two and a half years, upgraded the road systems of Kingston and St. Helena at least five times. What is up with that?
Secondly, while I was improving the roads in Sardinia, I decided I might as well get them a rail network. Since the railroad was finished before the roads, this invalidated my roads decision and it was cancelled. Which I find rather odd.
Also, can anyone tell me what I am supposed to do as SP during the Crimea War? I am currently giving the Allies my full emotional and moral support while keeping all my forces in strategic reserve (in Northern Italy) in case the Russians try something funny.
