I wanted to add that I am experiencing the same issue with the following conditions:
- Every time I leave a server and rejoin my character is reset.
- The above is regardless of whither I am on the same server or a different one.
- No one was around me when I left the server. (Including zombies)
- I recently opted into the beta steam client, however this did not start happening until today.
I hope some of this feedback helps so it can be fixed asap. I don't mind restarting after dying, or even misc. game glitches, but I don't want to have to restart from scratch just because I disconnected to relieve myself, or eat food(IRL).
