A couple days ago I finished the ancestral remnants quest. Right as I tripped the last trap, a Juju appeared. But since the Rock was congratulating me on completing the quest and I couldn't get rid of his dialog fast enough, the Juju got me. The same thing happened when I got the Twinkle-Toed Trap Triggerer achievement later on. I wish that when something important is going on in-game like that, where interrupting me is going to cause something bad to happen to me, the dialog from the Magic Rock or the announcement or whatever would wait until I'm done. (Maybe even if I'm in the ancestral lands, all the announcements are postponed until I leave, since I'm so time-limited.)
