2.9.5 Why out of supply?

[Gar-Dog]

With a graphic:
- Shows Rundstedt tracing supply through Foochow from Calcutta (note Shanghai is in the same SZ as Foochow, on rail)
- Shows Guderian 1 hex from Hyderabad, which should go directly to Calcutta then by sea to Shanghai
Running 3.0.4, bug is the same as it was in 2.9.5.

Thanks for checking!

Notice that Rundstedt use 4 non-rail hexes (Basic Path hexes) to get to supply. Guderian would use 5, since he has to use one to reach a hex containing a rail line. Hence, Guderian is OOS.

The program is correct, since only 4 Basic Path hexes can be in a supply line between units and a supply source, and between linked supply sources.

So the Japs and Germany meet in India! Wow. Really stressing the program.

But the million dollar question:
Why not trace to SHANGHAI or CANTON instead of FOOCHOW? Using FOOCHOW is the program error. These other major, rail-connected ports are in the same SZ, and also Axis-controlled; China is conquered. It's the worst possible port to trace supply to! Why not this supply route?

You would still have to go overseas - which requires a 5th Basic Supply Path Hex.

How about this, for two basic hexes (not five):
Guderian: India [89,97] (desert)
1R Hyderabad [88,97] (clear)
Rail India [88,98]
...
Rail Calcutta [92,116]
Sea Bay of Bengal
Sea S. China Sea
2R Canton [92,142] (or one more Sea to China Sea, then Port Arthur, Seoul, or Tsingtao - any except Foochow)
Rail China [91,142]
... All the way to Germany through Chengchow, Peking, Harbin, Chita, Irkutsk, Krasnoyarsk, Moscow...
Rail Konigsberg [46,45]

Uses one sea leg and 2 hexes Basic Supply as far as I can tell. Both China and Russia are conquered in this game.

Am I missing something?

I'm sorry, but I don't seem to be getting a direct answer.

The program is correctly calculating that supply through Foochow would not work. I have no argument with that. If Guderian traces supply to Hyderabad (1 basic), to Calcutta overseas, into Foochow (+1 basic, +3 to get to rail = 5 total), he's out of supply. No argument.

However, Guderian can trace supply to Hyderabad (1 basic), to Calcutta overseas, into Shanghai or Hong Kong (+1 basic = 2 total) instead, there are only two basic supply hexes used and he is in supply. The question is, why does the supply routing not go through one of these shorter paths?

Yes, that should work.

The code does have a limit on how far it will search to find a primary supply source.

I tried moving Guderian onto the rail line and the program still reported him as OOS.

Thanks for looking into it Shannon.

I understand this is an atypical game! Part of the reason I kept going was to stress-test the program, not stress the people... [:)]

With the "default" carrier air fix, maybe the Japanese can facilitate German supply via the Red sea now and bypass that bug... Their carriers kept running into that bug around the Indian Ocean at the same time. Was too much work to edit in a new supply unit every turn plus manually execute & then edit the carrier battles.
