The quest 'Fondness for Festivity (Intro)' will not bestow if you accept the quest 'In Celebration of Midsummer' before accepting the quest 'The Majesty of Midsummer'. If you have already accepted 'In Celebration of Midsummer', cancel the quest, accept 'The Majesty of Midsummer', and then re-accept 'In Celebration of Midsummer' to correct this issue. A fix for this issue ill be part of an upcoming patch.
