Extra provinces doesn't make the ai stupid. Its the poor or lack of coding inside the ai files and proper switching of ai files.The default paradox files included in aod.
I think the ai files in use now by aod are the 1.2 armegeddon ones without any other modification. I may be wrong. : /
Honestly, I don't know. But now I can look more closely into these files so I might assess your apprehension. But I'd expect that the devs have mostly concentrated on ai hard-coding.
Hundreds of missing airfields,navalbases, rivers, incorrect weather patterns and terrain inside the default inc and province files are also partially to blame for bad ai.
BTW, very nice job so far on this new map. Hope it becomes a new aod standard.
That is my hope, too.
