I have done what a lot of others have done. Completed a random for the day prior to the event start. Ok I won't get too salty.
However, i completed a random on my alt. I checked the reward was available (it was there in the rewards).
I finished the dungeon and as I looted the last boss my inventory became full. So I missed out on the reward again! Even after clearing my inventory and my mailbox....fml :'(
