In this week’s vault I (on my warrior Hellgaunt - Ravencrest) should’ve had 3 mythic dungeon choices (and 1 raid choice). I only got 1 mythic dungeon choice.
Is the Vault bugged or is that a known issue?
For the record I completed 10 dungeons between Jan 23-25
Did you forget to open the vault LAST week? If so, the first time you open the vault you will get last week’s reward. You need to open it a second time for this weeks as it stores uncollected rewards.
No I don’t think I did, but maybe the week before this I did that. Good call though - since my warrior is my alt that could’ve been the case.
Aha, then you should be able to open the vault again and you will get this reset’s rewards. 
Hey this was the solution. I had forgotten to open the one from the week before last week
Awesome helpå Shammoz. Thank you so much!
Great news. Hopefully the reward was something you needed… unlike mine this week!
