robust oyster
This is based on observations from people playing on my server, I haven't seen this myself. Basically they were playing just fine, then all of a sudden they de-synced and were kicked.
When they tried to log back in, the server said they were all still on the server, but no one was actually on it. When I investigated the terminal, it appeared to be looping session authorization tokens (server is up to date, otherwise they couldn't have been playing.) I've attached the logs and my DXDIAG.
Basically, it seems the session manager in the server itself got stuck in a loop of some sort. After restarting the Windrose server software, the issue went away. They could all log back in and found that time in-game had still passed. They were hungry and items they were crafting had completed.
Dunno if this helps, but just trying to do my part to help improve this awesome game.
