When I tried to get into game it had an outdated version of the game so I restarted the server and was able to get in game.
Noticed that the things I had been working on the previous day were missing. I had been rearranging 3 of my work stations (buildings) and 4 of my chests in one area. They were gone!
What happened here? Why would a server restart do this?
How often does the server save a players progress? When you logout I would "assume" saves your progress at that point.
