IIRC the Harper Quest starts off when you come across a poisoned guy, and have to take him to Rylock, and that should happen the first time you go out of Athkatla. This encounter never happened. Did I unknowingly install a mod that disables the Harper Quest?

And can I tamper with something to spawn that guy and kick off the quest?
And another odd problem - Anomen and Kelsey aren't doing what they're told.

That is, if I click for either of them to walk somewhere, they move a little bit then stop, so I have to keep clicking to get them anywhere. None of the other NPCs are affected. I
do have a previous save which seems ok, but I've done the Umar Hills and Trademeet quests since then, and I'd rather not have to do them all over again. Is there anything I can do?
I have installed: official patch, Baldurdash fixpack, Kelsey, Solaufein, Flirtpacks and Ease-of-Use.
