During the game I found myself unable to switch speed. When I tried to change it via speed box with mouse, it changed for a moment, then returned to 4-th speed back.

Also, later I found out that my chat messages were invisible to other players. On /ping command in list of players there was a register of me, but no username was shown.

It happened after several times of minimizing game to tray. I assume server somehow stopped to recognise me; yet I could control my units.
