Entering a dungeon while the “Dedicants Cache” stage is active resets the quest to the first step “Speak with Maka”
I confirm that. Also Bastions makes this quest reset too.
I have had to restart from “Speak with Maka” after the game has crashed while I was in the “Dedicants Cache” dungeon. I ran through all of the steps again to stand outside “Dedicants Cache”, town portaled, sold items, change configuration and adjusted abilities only to find myself back to “Speak with Maka” - I didn’t enter a separate dungeon, I didn’t complete any other quests, this has happened to me twice now.
It isn’t tracking the completion of any of the quests between “Speak to Maka” and Dedicants Cache. I have no desire to continue to experiment with the questline until this is fixed so I guess I’ll wait for Blizzard to confirm that I won’t be wasting any more of my time than I already have/am
