Not sure if this has been covered before, but CC should check to verify that fortification orders are not being double sent (e.g. assign each order some sort of random value, so if the same value occurs twice then it is a order-by-reload) ... for example, sometimes (due to my wireless connection) I get a timeout while I'm deploying. Before, if I just refreshed, I might (uselessly) deploy twice on the same country!
So now I'm very careful and if I get a timeout, I have to go to the main url, login again, revisit my game and such and it'd be nice if I knew I didn't have to do that. Pretty low priority, but ...
