Also running into this problem in my current game, playing as Soviet in december 42.
Dived into the numbers, an it seems there is definitely something odd going on. According to my Event Log I get 151,000 Resources. I have 228 HI.
As I understand it, each HI uses 500 resources to produce 500 Supply (this used to be 1000 => 1000 in the original, but is in feb. 2007 reduced to 500 => 500). There is a % modifier on this number. For the Soviets it is 130 in 1942. That would give an output of 650 supplies for 650 resources for each HI point. So with 228 HI points, I would be able to turn 148,200 Resources into 148,200 supplies.
But the log tells me:
90,915 tons of supplies produced in 228 HI centers (90,915 available)
31,977 supplies not produced because of resource shortages
90,917 tons of resources consumed by supply production.
It is unclear why the 151,000 tons of resources are reduced to 90,915 tons, or where the remaining 59,000 tons go.
In another report, the production screen, it gives me a Resource Store of 5,109,575 (125,400). No idea what these numbers mean, but it is clear I can not use these 5 million plus resources to do anything. The manual only tells me that the Resource Stores is the total amount of resources in storage (duh). It does not mention what the number in parenthesis behind it means, though in other cases it gives the amount needed to get to 100%.
Edited to add: my number of tanks and planes, verhicle, armament, manpower etc. produced are also reduced because of this supply sortage. So it is not only a reduction of power of the units due to lower morale and shoratge of suppply, but also a reduction of the whole soviet force due to lower production of everything.
