So what is going on in the picture below?
Is the HQ not giving supply because it is in a hex with only 1 supply? If I move the HQ back to the hex with 4 supply will it then be giving a supply of 1 within a 5 hex radius?

I asked this one of the first days. Apparently it was changed to give supply within movement range (I think), whereas the command radius should still be 5. Not sure why you're not getting supply here, however.
Weather will have an impact on movement and hence why the edge of the supply line shifts from time to time. You will need to factor that into your testing. Its interesting note the strategic importance of both ports Haiphong and Vinh. They would end the supply blues of China if captured in that area (There on rail).ORIGINAL: YueJin
There's some supply oddities that happen around Lao Cai/Haiphong if the Chinese move across the river turn 1. It blanks out a whole area that should be in supply, including hexes that previously were in supply on the opening turn. If you pull the units back into supply it starts flowing properly again. I'll try to get some screenshots today to illustrate it.
