There is a bug when loading automatically saved online games because of internet connection loss. The information in the list (player number, civilisations, date etc.) are all wrong and mixed up. Also when hosting the lobby most of the time all civs of all players are the britons, but that is just a visual bug. Once in the game, everything is fine, but in the menu, as I said, is the information false which is the main problem.
We all have the current version (November Update) and bought in in the microsoft store.
This screenshot shows the bug with all players being the britons and also when I started the game it was not the one it supposed to be - it was from another day, so the date and player number was/is incorrect!
