The Dropbox link in the first post leads to the most recent mod version files. I have deleted the links to the "hotfixes" of older versions. Is this what you meant, btd64?

Yes, I guess. It was just a little confusing to figure out which files I needed. And which files I didn't. Thank you....GP

Hi LST,

I've been using your ideas in my personal mod I use playing the AI against the Japanese. I have modified mine to embrace your economic ideas and your latest map. I want to report that I have found issues with mainland India's ability to transfer supplies, fuel, resources and probably oil to the island of Ceylon. There seems to be a land bridge there. I had to modify your pwhexe file to rectify this. You may want to check this as you do your testing.

You've put a lot of time and effort into your scenario and it does make the war much more realistic in the economic realities.

I do hope my biggest critic finds nothing in this post to whine to his masters about, however I fully expect that not to be true.

Hello DD696 aka USS English, thanks for your kind message.

The "issue" is actually a feature

Mainland India and Ceylon are connected by the "Adam's Bridge", a succession of islands, sandbars, reefs and shoals which in the past have formed a landbridge (apparently it has been destroyed by a violent cyclone in the 15th century).

At current sealevels, that landbridge is partly submerged - just barely, as water depth is between 1 and 3 meters.

Large ships cannot navigate in the area, but boats and small ferries can.

In fact there has 'almost' been a rail connection between India mainland and Ceylon, with bridges and causeways connecting the larger islands on both side of the Adam's bridge and a ferry for the 'missing link' of 22 miles in the middle between the railheads. It was a a vital lifeline for trade and travel between the two nations across the Palk Bay.

This ferry connection is represented as a "trail" (like I have done for the ferries at river crossing where bridges were missing), and since the two "railheads" (size 1 ports) are adjacent to each other, small amounts of supplies, resources etc. can be automatically exchanged between them.
