So I just finished "Exploring the Corridors of Time". When I returned to Saint-14 to get the next step for the quest which is Memento, the main quest disappeared and I can't find it anywhere. I tried it all over and I don't see it in my quests menu anymore. I've also completed other quests from Saint-14 and linked all of the obelisks to the tower and they are above 5 resonance rank. I've also seen people report this on Reddit and most of them are saying you need to do the quest with the same character that you used to rescue Saint-14 but I only have one character so this solution doesn't work for me. I hope you guys will help me out with this Thanks in advance.
