I'm currently at the Lorenzini Arcade and realized that I hadn't opened the trinity door at the factory; went over and found out that I was unable to open it despite being fairly certain I answered the guy's riddle and got it right. I was also able to open the door for the Cathedral and Opera House after getting the prior riddles for those correct so I know I didn't miss that one. I decided to backtrack to Malum district and got the riddle that I should have gotten if I had progressesd further and gotten to the grand exhibition. Am I just crazy and somehow misremembered doing that first riddle or am I somehow just softlocked from backtracking and opening prior doors after progressing the story? I'm just really annoyed at myself over this.
