My character won’t save any progress. It keeps going back to a previous save point. It’s been like this since the servers came back up a week ago. No matter how far I travel or long I play.

I exit the game normally.  Log into the same server and I’m not where I saved.  I’m back at the previous save.   Anything I’ve collected from that point has vanished.

I’ve tried uninstalling and reinstalling the game, going to a different server, the issue continues.
The only thing I haven’t tried is killing myself, and starting a new character. Don’t want to do that, I finally found an assault riffle and don’t want to give it up.
