Happened to me too. I was 10 hours in with 2 super chips and Tier II gear; I saved and quit so I could update my system, and now every time I try to continue from any of my old saves it spawns me back at the starting area with just a Pebblet axe, an empty inventory, and the superchips uncollected. My base it still there though. I am playing on single player with crossplay disabled, on the latest version of the Switch port. Is there any fix or workaround that we know of?
