Just an FYI that it appears for whatever reason the daily option to complete a personal story part does not work.
Last night a guildmate and myself who are leveling alts together did 4 out of the 5 daily achievements, and then decided to run a personal story part together for the 5th.
Both went to the same story part, completed it but neither of us got the daily achievement.
Would guess others have experienced this, could be related to us doing it together rather than solo but i shall try that tonight.
