I've compared all my Jamba quest settings, and they haven't changed. I re-pushed them for giggles with several teams. I see various strange quest acceptance behaviors as well.

Just left clicking the quest giver pops up the quest dialog now, and in some cases the slaves won't accept the quests unless I manual click accept on each one.

I've seen other odd beahvior, but unfortunetly I wasn't able to duplicate it afterwords to get a clear example.
