Yep, as the subject states, that's what happened.
Reading my Rift Season results and accidentally swiped over the little trash can. Email gone. No rewards claimed.
Sad panda.
Yes, Sir. Restarted app. No change.
Definitely no duplicate. Woke up to only 2 new emails; Medici PF and Rift. Deleted Medici as there was no rewards. Opened Rift email. Big thumb slipped, email gone.
Ya know, don't sweat it. Probably still had sand in my eyes and already claimed it...sorry for the trouble. Keep on keep'in on! (Maybe check your friend requests next time you're in-game) Peace!
