I am unable to complete the main story quest because I need to finish Ifrit, Titan and Garuda on Hard. The problem is in order to unlock those trials I need to do that quest "A recurring problem" that is given to me by Minfilla.

She used to have this quest when she was still in the Waking Sands but now that I've progressed far enough for the Scions to move to the Rising Stone she no longer offers the quest. Without it I can't unlock the trials and I cant continue!

Any advice would be appreciated
