Remember when Austin mentioned during the NMS stream that you can own freighters and send them out on expeditions now? Don’t do that. It will cause a corruption bug that will eventually nuke your entire save. Worse, it appears to be cross-platform, which means that people with potentially dozens of hours on old saves might lose their games with no recourse.
If you’re playing on PC, you can at least back up your saves manually. (Check your %appdata% folder, and look under the Hello Games subdirectory. I just backup the entire save directory as individual dated snapshots.)
(Off-topic: I actually started playing after the NEXT expansion … and it is mostly tedious? Like, the worst sort of inventory management, mats grinding, and F2P-style timers getting in the way of everything else? The on-boarding experience is pretty dismal as a new player, and there are entire game mechanics I had to guess at because the tutorials are so poor.)
