1.0.8.3 Supply broken

The German/Italian supply issues seems to be getting worse.
See below, the German forces in Marocco should be in supply through the Italian convoy in west med. Strangely, the Hungarian fighter (allied to Germany) is in supply. These supply issues needs to be fixed.
I have seen some other oddities with supply concerned
- British Inf at Malta reorganized at end of turn despite being isolated
- American naval units at Rabaul were out of supply despite having convoy link to Australia

Isolation is an optional rule not coded at this moment. So it is correct that the British INF is reorganised in Malta.
The other supply problems might be fixed (but not always) by saving and than restoring the game. There is a problem appearing with overseas supply sometimes in China/USSR too and this might be happening here too.

I just wanted to say hi to Gaute Birkeli. I liked your website when it was around….
I have played with No Isolated Re-Organization since about 1991, when a player in my group dreamed it up for a House Rule. I really can't imagine playing without it, 22 years later……seems like it should have been simple to add that one, and one of the most commonly played Optionals.

Picture yourself writing the code to check a supply line of unlimited distance...

That's already been done for the use oil phase for oil dependent units. So the basics are already there (use primary supply source instead of oil and OOS units in place of oil dependent units and there it is). Personally I think the supply issue should first be fixed, before coding this optional rule.

But the Commonwealth has a lot of primary supply sources (use F8 to see them all). And there can be a lot of units OOS during winter turns. That makes the requirement for the search algorithm to be much more efficient.
One of the worst cases for tracing secondary supply sources to primary is with the Commonwealth controlling Baghdad without any overseas routes and Germany at war with the USSR. Then the search space includes all of the USSR, with the British trying to find a path to India through China and Burma. Murmansk and Archangel are also possibilities if there are convoys in the Arctic.

You could choose to check this only in the reorganisation phase, thus minimising the time needed to calculate this to once a turn (maybe give the player a button to use for checking this manually if they want to). I know you want to check for this during the supply check itself, but I think the calculation time for determining supply together with isolation will simply be too much for the game to handle. Not everyone has got very fast hardware. If you get an awful lot of supply sources, MWIF already has a long supply calculation time, needing up to 20-30 seconds between movement of units (as happens in my "stress test" games)... I don't think we should put Isolation in this calculation too.
