Thanks Hubert, your last paragraph matches exactly my understanding of how supply chaining is supposed to be working, for HQ that are far enough apart to not to have supply available from resourses. I do not believe this to be working correctly (or at all) in 1.02, here are two screenshots showing this:
scgc102example2.png Here the 3 German HQs are all able to get at least 1 point of supply from the Finnish HQ in Leningrad, hence should be promoted to 8 supply as per the table.
scgc102example3.png Here supply comes from Smolensk which is at 6, and this reaches the southern of the 2 German HQs and puts it at 8 supply. The northern HQ is out of range of Smolensk, but according to the table it should end up with supply 8, not 7, by chaining from the southern HQ.
I will mail you the save files from these two situations for you to examine.
But isn't this supply improvement also supposed to happen for HQ that are closer together, e.g. the HQs in the first screenshot I posted above?
Since you think the rule may have changed since WaW I'll leave it out of the discussion, though I know there was HQ chaining in WaW.
Thanks,
Barry
