I just had something stranged happened to me, twice.
I was at the summoning stone outside MV, mounted up, like 10-15 yard off the ground. Suddenly, I was pulled into the air, then pulled into a mountain nearby, needless to say as soon as I touched it (I was still on my Ashes all this time), I was dead from fall damage. Not only me, 3-4 people around the stone at the time, also died the same way.
So I Ankh, rez'd my friend, suddenly we were pulled again, this time into the quest area where there was that stone table with the book on it (and loads of stairs nearby), and died again from fall damage as I reached the place.
Non of us know what happened, has this happened to anyone before?
