Well, I want to apologize for the misunderstanding...
It seems that the problem is still in the game itself (((
I tried playing without HD - the same thing happens. After some turn, all saves become corrupted... :(
I loaded the last working save, saved again on the same day - and this new save loaded normally... But after finishing the turn (even without doing anything), on the next day and further - all saves are corrupted (((
I don't know what to do... I even downloaded the original SoD in English, and on a computer with English XP, I installed only WoG in English without mods/expansions. I even renamed the map to wogify_random_map_1 - nothing helps (((
And it's a pity to give up, I spent several days on this map(((((((
Maybe someone can advise me?
