Salut
The scores are not saved anymore once the civ3X.bix file has been modified, even if you only changed city names, or the French color
In fact I think the scores of a modified scenario are not recorded anymore because you could have changed things to have a bigger score, and then it would not be comparable with the other scores.
I wonder if the scores are still recorded in the vanilla Civ3 when the civ3.bic has been modified ?
