1. On the calculator, You need to provide an actual attack and defense force for comparison.
Just saying that, “oh this one time i had calc results and then my actual battle and some other calculator didn’t match it”, really doesn’t give us anything to go on.
So far, in all instances provided, triplea calc has shown itself to give accurate results.
In addition, it is worth mentioning that if another calculator and triplea’s calc disagree, it could be the other calc that is wrong. So you should solve the battle mathematically too.
2. Are you using the “Battle Map Skin” for Global 1940?
I specifically made a map skin using the battlemap board, the battle map units, and the battlemap colors, for you and the other battlemap diehards to use with triplea.
It is included with the “bundled” download, and I’ve posted in multiple places how to download it (if you don’t already have it) and how to use it.
3. You can change all art and all colors and all files in the map’s folder or zip, without affecting any saves or games or anything. The only thing you shouldn’t touch is the “xml”.
