-After defeating Gharj on the next try only 3 people got their weekly quest updated. No one died on the encounter.
We had this happen 2 weeks in a row. Are you sure it wasn't 4 people? As far as we could tell, group 2 did not get their quest update. We're going to check for sure, next week.
If anyone else knows, please speak up, because I'd like to get this solved, so Bioware can fix it.
