Hey, at first, nice work, thank you!
I think there is a bug in the English version. The text, for example when a train has stopped, is in French and not in English.
An AFK button would be very helpful if you want to get a drink or something else. You press the button and then the AI takes over your job for max. 5 minutes. After the 5 minutes the player will be kicked from the server and can rejoin if the player is back. If you are back before the 5 minutes are over, you can simply move on
That problem was at Bedzin. I asked other players but they don't had this issue. After some minutes it fixed itself. A rejoing hadn't fixed that issue.
