The first diplo phase allow to send Amb overseas and declare missions, then those dipl. actions are resolved (England declares war, Neutrals swing towards one alliance..), but then "another" diplo phase kicks in, it says I can send Ambs now, but I can't !
How is that supposed to work ?
Edit : sorry, in fact it works, I can send diplomats again, I just forgot the Amb button (damn this interface !)

... But why do we get 2 phases ? Only to be able to react to the 1st one given the broad spectrum of possible results ?
