Allied supply through Russia

[jesperpehrson]

CW controls all of Iraq and Persia.
CW has a convoyroute from Liverpool to Archangelsk. Archangelsk is controlled by the USSR and has a railline to the Caucasus.
It is raining in the Arctic.
CW has a HQ in Baghdad.
Germany and USSR are at war.
There are no allied convoys in the Arabian Sea.

Should the CW HQ be in supply?
The game shows it as out of supply and I cannot understand why.

[Courtenay]

There is a known bug that limits how long the rail portion of a supply line can be. However, I would have thought that Archangel to Baghdad is less than that limit. However, it may be that you ran into this limit.

A saved game would let us understand things much better.

Just an idea, are the rail lines in Persia and Iraq free of enemy ZOCs (including partisans)?

[jesperpehrson]

It is the same save as the bugged russian HQ.
All rail-lines are open.

After looking at the save it looks to me that the HQI in Iraq should be in supply through the link you described. And that Teheran should be a secondary supply source for the SA TERR in the city (as CW has conquered Persia).

However, there is a limit in MWIF on how long a rail supply link can be. I think it used to be 30 hexes, where each sea area counted as a hex. And this route is way longer than that. I am sure someone can enlighten us on what the current limit are.

Anyway. I do not think it is a bug. I think it is the MWIF supply limit that you have reached and passed.

" France and the Commonwealth are unlikely to be successful tracing supply through the width of the USSR to a primary supply source, so for them the search distance is reduced. "

Maybe change that 40 to the minimum number of RR hexes from the one west of Bushewer to Archangel?

I changed the 20 to 60 in the above code. The default maximum search distance is 400. The code in my previous post changes that in some circumstances.

Shouldn't all the Western Allied MPs have the same supply limits? It feels weird to me that a French HQI could be in supply in a situation where a CW HQI is OOS and so on. Or having to send a US HQ to bring supply to an area where a CW HQ can not.
