Yesterday, twice while trying to obtain my Bard Relic (Titan HM), I 90ked. When I tried to log back in, both times I would hear grunting while the login was occuring and when I'd get back, I'd still be in my Titan group. Also, both times, my character went invincible while I was 90ked. My team members said they watched me get hit by landslide and not move or take damage.
