Hello,
Rest assured, I have already submitted a report to the developers with your complaint and your suggestion on fixing the event; no further encouragement is needed. I apologize for closing the previous thread. I had thought the matter was closed and handled since I made very clear that I intended to submit your suggestion, and there was no reason for me not to do so. I will keep this thread open for a time so that you may continue to ask further questions.

As for the questions posted here, All information about the event in question (Matsuri Challenge Arena) can be found in the event's information menu and on the event's UI.

Thank you, and if you have any further questions, please feel free to ask!

I will be sure to amend my report for this submission to reflect a change to the instructions for you! Thanks again for your suggestion!
