Uh oh. I've got a nasty problem that I don't think anyone has gotten to yet. This is on a standard R4 with 1.23 firmware, I believe. Anyway, on day 74 ("Trio"), to not give anything away, you have to search for "someone" in Twilight Town, and you're told to investigate a place called "the usual spot". Anyone could tell where exactly they want you to go, and I went straight there, but absolutely nothing happens. I can look at the things in the room, and just nothing happens. I've combed through the whole area about three times and found nothing, and talked to everyone a few times. I've reason to believe that somewhere along the line, an event flag was removed to prevent progression through the game from that point.
I may be wrong. There may just be some tiny little thing that I couldn't find in the level, but I sincerely doubt it since the game pretty much told me exactly where to go, and nothing happened. If anyone has any info about this, I'd like to know.
