I updated the original post with the results of the two FM that have been completed (Absol vs. mrpaper & Absol vs. Kakerlake).
NikaZaslavsky & xdude having not answered and having a huge amount of Relics to catch up... I supposed you don't want to continue
The FMs involving players who surrendered have been cancelled, which raises a problem :
Two matches (drolly vs. Onizuka & Kakerlake vs. majofa) are unchanged. For the first one, Grid will be available in the first post in 10 minutes.There are three players left alone with a FM : Helston, annamall and Onizuka.
I can of course schedule a match between two players, and the last one will be left.
Same goes for Round 7 : 11 players chose to continue, and one of them will be left alone by the pairings.
I found two possible solutions : wait for another player to be eliminated after one of the two running FMs (which doesn't solve the lonely FM player problem), OR asking for a very kind player to play the matches for... nothing.
Suggestions are welcome, as Round 7 awaits
EDIT : Found a third solution : starting Round 7 with 11 players, and the lonely player plays against the lonely player of the Floating Matches. But that may imply an awkward glitch between round events.
