For the fast moving thread, a few hours back.
My game crashed as I was saving at some two bit shack that I had just walked out of after leaving my ship. Rather than load the previous (2 minutes?) save it pulls both saves off the cloud. I've lost 7 hours, a newly charted system and one heck of a new ship. I feel sick.
So, apparently my game is ruined. I've been playing for the last three hours. I noticed around 30 minutes ago that my save timestamps hadn't changed since 12:10, a little more than three hours prior. So, I took precautions. I saved while connected, then saved after I'd cut the internet.
When I restarted, I restarted while I was still disconnected from the internet to a three hour old save. I connected, hoping against hope that maybe it would have saved (even though I knew the timestamps hadn't changed. Nope.
I'm loving the game but I don't know if optimism is going to be enough to keep me going if it's going to be a No Man's Sky rendition of Groundhog Day.
edit: Now that I've reread my original comment, I'm beginning to think the cloud has nothing to do with it at all. The game just isn't saving.
