First The Selene's Web group dungeon normal mode - bugged quest which, once picked, didn't spawn Bosmer npc in marked location. Happened also to another player from group. We finished dungeon and I got an achievement, but the quest obviously was not completed.
Question is, will it be available to me when I queue for this dungeon again or it's already lost with completing the achievement?

Another one, inside dungeon two of our group players lost their group&player marks over their heads. As a result I didn't know if they are enemy or ally in next fights.

Another one, dead npc can't be looted, no matter the distance from target. Upper-Right corner message keep spamming when I try to loot. Only Reloading game helped this.

Last one, Vault of Madness group dungeon normal mode, being hit by Grothdarr boss' spell over 28k damage, more than my health, so quick I had no time to to block (I played dps/heal) - one of those headshots granting instant death. Isn't it fishy that one Firepede hits for 7492 dmg and is followed by another Firepede of 28248 dmg? Total damage on recap ~46k, when my health less than 25k
