I seem to have found a bug in the Random Daily Dungeon system. When I try to do a random Daily Dungeon with my husband, I do not get the random daily dungeon credit mail and rewards (while he does).
This has happened twice now.
My husband invites me into a group (consisting of only us two), and he is the leader. He opens the party menu and selects 'Group Finder' and queues us for a random daily (normal) dungeon. When Group Finder puts us into a group, a message pops up on my screen telling me that I will be healer in XYZ dungeon, and I select 'F' to accept and teleport. I am teleported to the dungeon and complete it with the group as normal. At the end, I do not receive any mail or special XP for performing the random dungeon.
The Group Finder on my ESO is still marked as though I have not completed my random for the day.
I would also mention, in case it is important re the bug, that in both cases the Dungeon Finder seems to have matched us with another existing group of 2 players rather than 2 other un-grouped players. I noticed this, because on both occasions once we got into the dungeon my husband was no longer the group leader and one of the other players was instead.
Has anyone else experienced this?
