Outcome confirmation
One of my players misunderstood the process and picked an outcome for his scene before writing his final text, rather than the other way round, which meant that he couldn't actually write any details of how things went wrong.
Could you include a confirmation step before processing an outcome, something like 'Are you sure you wish to choose this outcome? Choosing an outcome will end the scene and no further text can be written.'
That would help head off mistakes like this, and maybe prompt players to think about the most appropriate outcome before proceeding.

This should no longer be an issue, since in Alpha 2 outcomes are a part of moves.
