Yes I agree that there should be a limit on how meny quests per a thread
but remember this time line shoudl only last for 20 years
and thus far it has been a few weeks already and the group is on the second quest.
there has to be a slow-down and some tiem to pass between quests, or at least the time needing to complete a quest is much longer. Lets say that the second quest is part of a series of places, which in order to find these places 'research' has to be made to find those places, which could take a good amount of time.
