Lost Legendary Crests

Entered rift used x10 Legendary crests, right at the start I was leaving the just just before entering. It counted as I quit after it started bec. Of lag. Neither got my loot or crests back from mail.

pretty vague, my guess you havent waited and they prob been returned by mail, can take few to 30 min

This is one of the most often reported things on the forum.
The crests will be returned in the in-game email.
This does not happen immediately, it can take a while.
You have not lost the crests.
