[2021] logout to main after 10 min of playing

This hints at the server not being able to keep up with the connections and play of the affected people, either due to being too weak or the connection not being strong enough. Every 10 minutes the server calculates world ticks and sends them to the users at once - this requires both a lot of CPU power and causes a burst in network activity.

The only fix for that would be getting a more stable and powerful connection or, if it's a performance issue, a better CPU. (Or hosting on a dedicated server or a GSP)
