Thanks, that explains it. I went there now and the "edit tournament details screen" doesn't show arena draw options, so I don't think you can change this once the tournament starts.
Another small thing, after I started playoffs it took me 15 minutes to find the page to manually adjust seeding to break ties. Maybe I was looking in the wrong app (organiser v scorekeeper v match play live). I can't remember where I found it now. Can you remind me?
I just ran a test on this. I created playoffs, then a screen told me "Ties have not been broken below. Make sure you are pulling the right players into the finals tournament and adjust the seeding before you start the finals tournament." But I cannot find where to go after this.
Loving the software!
