Very similar thing happening to my son and I. We were in the Pirates cave earlier, I died to the trap, but he rezzed me. We played a little longer, then had to stop and save due to work time.
Now we're unable to resume the saves. I can make a new game, save, and reload fine, but the Multiplayer Save game we had (multiples) no longer work after we went into the Pirate/Orc cave.
