I was tabbing the Samford hs policy tournament last weekend and noticed a potential bug -- all the settings were correct (triple checked all of them).
In Round 6 of Novice Policy, there were two teams that the computer refused to pair on the correct side. It appeared that it valued no pull ups over side constraints. We had to hand pair round 6 to correct this issue.
This past weekend at a tournament I was at (Alpharetta Treasure Hunt) I noticed side constraint errors again in policy debate. I was not in the tabroom though and I don't have admin privileges to it so this could have been a setup error.
