Missing Lightspeed Token Quests

Hello, all!  I am a fairly new player (I joined during the Era of Anniversary) and am experiencing a problem with the Lightspeed Token Quests.  After Darth Vader (Duel's End) was released, I stopped receiving the Journey Quests.  I have talked with EA Help and haven't been able to get a good answer on why this is occurring or how to fix it.  Does anyone have any more information on this issue?
