ARAM REROLL BUG
Played an ARAM in a 5 man premade and re-rolled twice during champ select. One member from my group failed to select a champion and then my friends and I lost our rerolls. Only the dodger is meant to lose them. Oce please fix.

No, this is intentional. If your team was refunded their rerolls you could dramatically increase your chances of winning by everyone rerolling bad picks, and one player taking one for the team and dodging when the team comp wasn't as good as you wanted.
