You enabled motorization on an army level, which means every Supply Depot in range uses trucks, 250 each. Make sure to only use motorization where you actually need it

Thank you for always responding - no doubt a thankless job.
1. Each Depot is 125 and 250 if you do the triple truck icon (doubles it). I did not know that, I assumed it was the number of units. So if its by Depot, whether you have a division with 2 Infantry or 15 Panthers, it always draws 125/250 trucks. Is that how Vanilla works? Anyway, thank you for that. I do see the individual hubs showing the 125/250 truck thing.
2. Here is what I believe is out of wack - I (Germany) had 13 divisions (need 28 Supply) sitting on the Maginot line for a long time. As a test, I clicked the truck icon for this 13 division army stationed on the Maginot and this activated 1500 trucks. I clicked on Supply map mode and saw that this activated 12 of the closest Supply Hubs.., so yeah, that is way wrong. and the Train links that light up in red when you hover over a unit.., that was jacked up.., too hard to explain that part, but it is not working at all.
3. I think that every Hub that could reach a unit with Supply will activate for the entire 125/250. In my situation, a single hub is more than enough to supply the 28 needed for the small Infantry army on the Maginot.
4. You know what,, jeezus,, I am playing around with the Supply map mode.., it is soo broken. I can tell someone increased the Rail lines from Berlin to compensate for this.., hey man, whatever, it sort of works...,

Yes, as said, dont activate Motorization on an army. Activate it only for the supply depots in the area where you need more supply.

Your 4. Point is wrong, there is no railway for gameplay, its historical placement

Bob...., oh man! I was using the Truck for the armies and army groups. I did it by Supply Hub as you said.., YEP, works. That should be stickied somewhere, that is pretty significant.
