Bug #26848 for Games-Tournament-Swiss: C8, C10, C7 infinite loop

C8, exchange 261: last S1,S2 exchange C10,re-pairing Player 28 in Bracket 2 C7, last transposition C8, exchange 261: last S1,S2 exchange C10,re-pairing Player 28 in Bracket 2 C7, last transposition C8, exchange 261: last S1,S2 exchange If there is only one player in the last bracket, it should be giving them a bye, unless they already had one. This I found in the morning after running overnight to force out a C13 loop, where there were no downfloated players. The unpairable last bracket was 3, but players were 24, 25. I would need the YAML files to reproduce this.
