Bug or Error Support! – Sailor Moon Drops Review

Dear Bandai, there seems to be a game error on the 2nd Anniversary Special Event. I understand you don't communicate per game tips; but, this is not a tip. I think there is an error on Course 5 Stage 2. Please know I am communicating in good faith and charity and not seeking game tips at all. I play fairly and honestly. I'm an experienced RPG player. Allow me the opportunity to get to reason for writing. The reason I write is because I believe there might be a bug. There is no key to collect on Course 5 after completion of Stage 2 after all other courses are cleared. If I am incorrect, I apologise and won't bring this question up again. If I am correct, will this bug be fixed? Thanks Appreciate You and Kind Regards. JenG
