As Summoner, I'm having issues with this quest. Googled the issue and see where some folks have had issues in the past with this quest and the recommendation was to ensure the 2 prerequisite main story quests have been completed, which they have.

Upon looking at the cut scene video I have a theory on what may have happened. As I completed the previous main quest, The Least Among Us, I skipped the cut scene. Watching the video online, it appears the quest I'm missing, A Time To Every Purpose, is automatically generated in the cut scene itself, not after the fact.

At any rate, The two prerequisite main quests were completed. It accepted and completed The Least Among Us, but did not initiate the A Time To Every Purpose quest. I even went to promenade where I was supposed to go as part of the next quest for kicks and giggles, no luck. Minfilia is still inside the Rising Stone with no quest options (turn in or new) and I have no Main Quest in my journal.

Any suggestions?
