Why does your rerolls disappear if someone dodges in aram?

I think this is a bug. I experienced this the other day and lost both of my rerolls after someone else dodged. I would recommend sending a ticket about this if a rioter doesn't notice. Feel free to say others have had this issue (because I, myself, have).

Riot already knows, and (hopefully) will have it fixed next patch. In the meantime, finish an ARAM game or close/reopen the client to get them back.

They shouldn't disappear if someone else dodges. Unless you were queued with them maybe. They only disappear if you dodge to my knowledge.

It's not supposed to do that. Normally it works just like Skin-Boosts when someone dodges or you even you should get refunded.

It's been happening to me as well. Ever since I downloaded the new client I have lost re rolls in ARAM when solo queued, and other players dodge. I've lost 3-4 re rolls this way in the last week.
