Another ceded province bug probably related to the previous; and probably related to temp access, since I don't think the game behaved this way before.
France is at war with Russia. France owns several Austrian provinces ceded after earlier wars. Russia is also at war with Austria, which should not be relevant, but perhaps is, as we'll see in a moment.
Russia moves forces into one of France's ex-Austrian provinces (W. Galicia, if I recall correctly), and drops a factor into garrison in the capital. Next turn it gains ownership of the province. So far so good.
Then France moves forces in and attempts to besiege the capital. The game says I can't.
The only thing I can figure is that the game is treating the province as "really" Austrian territory. I can move around in it, but I can't besiege. This would seem in line with the previous post, in which we saw that a power at war only with the original owner could move in.
I wonder: if I didn't have forced access to Austria, would I even be allowed to move around in this now Russian territory? Similarly, if Russia hadn't been at war with Austria, would it have been able to take the province from me in the first place? It should be able to, but the game seems to be treating ceded provinces as still owned by the original owner in inappropriate ways.
The only ways in which a ceded province should differ from a conq'd minor are A) the owner can't draw manpower, and B) if the original owner reconq's, it becomes an unceded province and can only be lost again by ceding. For access, change of ownership between non-original powers, sieges, and everything else, it should be just like a conq.
