So here's the replay (see turn 6):
In summary, I have a fling with the ball that I throw, hitting the opponent goblin and injuring it. I pass my armor check but even though I have dropped the ball, I did not suffer a turnover... I guess by a literal reading of the rules, I did not fail my landing (I never rolled it, hitting an opponent). Is this the correct implementation of the rules or is this a bug?
