Buggy Morlanth

This past weekend I repeated the Shroud of Souls quest line for the first time since it first came out. And whoa, was Morlanth (the last boss) ever bugged! Specifically, she didn't do anything when I attacked her - which would have been fine by me, except that this "not doing anything" also included "not dying". She just kept standing there at zero health.

When I googled the problem I only found this off-hand mention of someone else having the same issue and apparently circumventing it by attacking her really, really slowly (once every ten seconds by their own account). I Alt+F4ed to reset the fight and tried this, but without much success - if I waited too long between attacks, she would kill me (rogues aren't made to just stand around while being hit in the face), and if I tried to attack a little faster she would freeze up again.

Fortunately, after Alt+F4ing for the fifth time or so, I suddenly loaded back in to find the giant dragon that she summons at some point into the fight in front of me, and that one acted like a normal enemy, so when I killed that the quest completed. I'm just putting this here in case anyone else struggles with this bug...
