I have earned exactly 100 Vanguard marks and have attended events to earn more Marks. However. no achievement still. I earned my 100th Mark last night and was hoping that logging on this morning would unlock it. I would really like this to be fixed because I am not going to have as much time in the future to earn a weekly challenge such as this and I grinded very hard for nothing. Would appreciate a comment so this can be seen and noticed by Bungie. Thank you.
