First off, this update is amazing. I am loving the story elements, they are fantastic. I have encountered what I believe is a bug however. In chapter 3, I have the rival task of "watch all the Phantasm Facade events," however I have completed all the events that have appeared and I still cannot complete the rival task. Additionally, once I completed "story_chapter_3_event_6," the background music and interface switched back to their state in chapter 2 and I don't seem to be able to progress any further in the rival's story. I've tried manually re-triggering story_chapter_3_event_6, and the event plays with the idols, but the rival's task still cannot be completed. I don't know if this is a bug or if I am missing some requirement to trigger the remaining masked group events and rival events.
Regardless, the game is still amazing. Thanks for all the exceptionally hard work.
