On turn 38 I still have 1 army with 0% supplies. Can someone explain this?

Oops! Still, it would help to see the map and examine it with the eyes of a Polonvik of the ShtabORIGINAL: Oshawott
I wrote in my post that distance to railhead is either 0 or below 8MP.
Where's Nelidovo and Olenino? Show us map. Maybe cut-off cities are selected for supply centers? Or not connected to rail system?
