I was playing around with the Serco Training 1: Basic Flight mission. It tells you to hit launch and not touch anything. Then it tells you to keep holding "w" and then to keep holding "s". Then it tells you to hit "m". The mission computer then repeats what it told you in-station and to press launch. You are obviously already in space and therefore can't launch. Even if you re-enter the station and relaunch, the mission will still not progress to the next stage and therefore cannot be completed.

I can confirm this bug. I was watching a friend of mine learn how to play and he was totally confused on this mission (Training 1: Basic Flight) when it told him again to Launch from the station while he was in space. I'm certain this mission worked a few weeks ago when I tested it, but it seems things have been gotten mixed up in that time.

Would be well to fix this minor bug to new players can finish the basic flight mission

Heh, oops. Should be fixed now.
