I used the group finder to run this mornings normal pledge in Darkshade. Never mind we had a level 22 in the group which should be impossible for Undaunted runs because they need to be level 45 to get pledges.. But I was trudging thru Shadowfen for 30-40 minutes and started a dolmen. About halfway thru the initial battles I get prompted to join the group. I have two options [F] Teleport now, [X] Hide message. WTF? I can't pause until I finish the dolmen? So I tried clearing it.. killed the boss and before the chest dropped.. Poof! Darkshade Cavern. Finished the run, went back, and the dolmen is marked undone and I have to do it again. Stupid UI design seems to be the hallmark of ESO. Do you guys have contests for that? "Heh, I bet we can make this fail! Watch!"
