in group 1, I invited the wrong people to matches 2,3 and 4. One player ended up playing two matches during R4. Those were all proper matchups but from R6. I will resolve this by inviting the needed players for round 4 matches during R6 which will result in one player not playing that round, and one player playing two matches that round again, but we will still have proper tracking by the ned of the round robin phase.
R5 will proceed as it should initially.
