Ok. 300hr+ new Beyond, PC, Steam, Normal, Non-VR, non-3xperimental.
Manual saved at my base. Waited to make sure I got the save confirmation. Logged out for the night. It was after midnight. I had just completed a tedious solo Nexus mission on the most unpleasant planet I have yet to come across.
It involved killing hazardous plants, which were few and far between, on a highly hazardous mostly water/bogs planet. That meant a lot of ship hopping, getting out and scanning and maybe killing a couple plants and flying to another land mass, etc.
I was jumping in and out of my ship a lot. I even put a Save Beacon down on a Trading Platform and saved manually more than once. It was too late to take the time to hand-in the completed quest, so I decided to wait until the next day (today).
This afternoon, I logged back in and found myself in the Nexus, not in my base where I logged out. And with no quest to hand in there.
I checked my last save times in Options, and they looked correct. I thought ok, just a glitch. And I relogged into my last manual save, which was what I had expected to log into before, but it logged me back into the same spot next to my ship in the Anomaly.
So I tried the auto-save which was just before midnight. Put me in the same spot in the Anomaly.
It was as if starting the quest for the Nexus had put me into some kind of instance for a couple of hours that disappeared when I logged out after completing but not handing in, and essentially put me back to where I was before I took that quest. --without changing the times of my last game-saves.
My brain is reeling!
The weird part is that I have been having Windoze back up the HelloGames folder in %AppData% every morning. So I quit without saving, put steam into offline mode, and restored from that and I still logged back into the same spot with the same saves listed.
So, was it a Steam glitch? A HG rollback? Or a Nexus peculiarity? something happened. I just cannot fathom what it was. (and that bugs me!)
(also, I will never do that quest again, unless it sends me to a more pleasant planet next time!)
