If I manage to load a savagame I can play it without any problems. The game does not crash during playing. However, when I save the game and then try to load it, it crashes to desktop. It does not matter whether the aforementioned savegame is loaded from steam cloud or my drive, the result is the same. I attach two savegame files: first, called atsv_backup.ck3 is the furthest working savegame I can load. The second file called kaiser_lost.ck3, generated a month or so after the former file is the crushing one.
