I installed an Age of Empires 3 mod called Abstract Nations Plus (Restore Monarchy). It is working well except two civilisations are not showing up in the skirmish menu Austria and VOD. The developers had a fix here:
If VOC or any other nation does not appear - either completely clear the ‘C:\Users\***\Games\Age of Empires 3 DE\***\Savegame’ folder, or find the ‘sp_Mao#NationName#’ files and delete them specifically. Before starting the game, disable Steam Cloud synchronization.
But it didn’t work. Can you assist me in finding a way to get it to work?
