If your reliever pitches 2 innings in the last two games of the series, he will not be available for game 1 of the new series even if several rest days occurred.
Apparently, the same bug affects starting pitchers if you want to use them as relievers. My team is facing a team that has Darwin, and I have a bunch of righty bats. Darwin pitched in game 3 of the preceding series, and his team had then 3 days of rest, but because of the bug, Darwin was not fresh and needed the first three games of the series before becoming available.
I must admit it gave a break to my Lineup!!!
