Another cosmetic thing: one of the game hints states that "you may resume the construction of a fort if you are interrupted". I believe it requires some clarification: in my experience, you can only resume the construction of a fort if you have cancelled it, but haven't lost the province in the meantime.

Losing a province will effectively cancel all progress made on a fort (unless I am grossly mistaken here), while some players may expect to be able to continue building their fort at no extra cost. Or perhaps it is just my interpretation of "interruption" as in "lose the province temporarily due to enemy forces".
