I'm currently invading Prussia as France and am starting to run into some major supply issues. I've got an unbroken chain of occupation from Hannover to Magdeburg to Berlin and even past that, so there should be a good path for supplies, but none of the supplies currently sitting in Hannover seem to want to move into occupied territory. I've also taken Braunschweig, which is right next to Hannover and has a depot in it, and supplies still won't move into there. I've got something like 2000 units of supply sitting in northern Germany while my army is on the brink of starvation in the east, and I can't for the life of me figure out why the supplies won't move over there.
I thought it might be some weird interaction with part of the supply chain to mainland France being part of the Hessen network instead of French, so I built a depot in Hessen land under French control, and that depot filled up with supplies just fine, but they still aren't being passed on to Prussia. I have no clue how I could ever possibly be expected to make it all the way to Poland under these conditions. Am I doing something wrong?
Here's my overall situation. As you can see, I have a full line of supply from France to Berlin but no supplies stockpiled anywhere in Prussia (Stettin was just conquered, so those are captured supplies):
Here's my newly made depot in Hessen. It's working perfectly normally and seems to be sending and receiving thousands of supplies per turn:
And here's Magdeburg, which like everywhere else (including Hamburg) in occupied Prussia is not sending or receiving any supplies whatsoever:
Is this a bug? Do occupied depots not work and I should be building French depots in occupied territory? I have no idea what's going on here.
