It's early April, 1758. My army is concentrated in Konigsberg. I've upgraded the depot there to level 4. I've also built a level 2 depot at Ragnit (two spaces away), which tracks three regions to Memel. Memel then pulls from the off map Kurland box. I would have built a depot at Wierzbolow too but it won't change control, and I was reading another thread on here that said supply wasn't accumulating on depot's in polish territory.
My men are starving. I've built extra supply wagons and sent them in, but that only gives them a extra turn of survival. Now all supplies are gone, and units are starting to disappear.
Hopefully this is user error and not having anything to do with the game itself. Any advice would be appreciated.
