Yes Jamba has some issues with questing, for sure. I noticed that on escort quests if I open the quest pane on all slaves and then have Jamba auto accept, ONLY the person who is leader gets credit for it when it's done. However, I found out if I dont open the quest window on the slaves it will work. I recently had 2 slaves miss out on a quest because Jamba said they accepted it and it wasnt until I finished it and ran my ass all the way back that I saw that, no, they didnt accept the quest. Very frustrating.
