Save games not shown in build 54

This is build 54. Played the first map, game autosaved 3 times, got the promotion to the second map. Build like 30 houses (100+ people), prefects, engineers, farms, granaries, market, temples, saw the game autosaving a few times. Building my 3rd temple suddenly the game crashes. Restart the game, load game, only the 3 autosaves from the first map are there, nothing from the second map.
