Out of tournament, don't know why, help please?

I'm in this tournament, which says #advance=2, and I came second in my group, and it says I am eliminated. Why is this?

The tournament is now in round 5

This is standard behavior. if there are only 3 people in a group, then only the top 1 will advance. This is to prevent tournaments from going on unnecessarily long.

Would have been nice to know that ahead of time. Otherwise I wouldn't have offered the draw (I am wiseguy's opponent by the way). Is this procedure documented anywhere?

Would it be possible to have our game un-drawn? He deserves to fight to the bitter end and hope for a 3-3 tie in the round and advance to next round? Or is there a next round? Doesn't make sense to have a next round with just 2 players in it (there are only 2 pairings left in round 5). If no next round, then I guess it doesn't matter...
