I ran into all the problems you've mentioned when working on True Pacific. For a while, I was forwarding findings onto Starshoy, and a couple of small bugs got fixed, but then he stopped responding and dissappeared. I finally gave up on modding DGen after I figured out that some of the missiones (such as the carrier-based Bomber Intercept) simply did not work for one side (or both). Tough to have a Midway campaign where you can only run scrambles . . .
Nimits, I am in contact with the Russian guy who is working on the new DGen.exe. If you want to make a list with the problems you encountered when working on your True Pacific campaign, I can send it to him, maybe some of them can be fixed.
