I havent come across issues so far? Who are having issues?
we had several cloud saves get corrupted with a Civ6 update. We were able to roll one of them back the last save (lost about 3-4 turns) but another was only 10-12 turns in so we just restarted it.
I've had problems ever since that update with every new game that I'm in - when it saves and commits the turn to the cloud, it crashes the game.
