I myself can confirm as well that I wont be able to obtain the S rank medal at all, because of the center leaf issue. Like everyone else, I wasn't able to move forward due to being halted from getting the minimum of 3 globe chairs, though afterwards, and I jumped to level 6 immediately after from obtaining the chairs which must've sparked the issue. I never received the quest for the first tier of the bronze leaf at all nor any others so forth, even after obtaining 5 S rank materials for the given category. I have all S materials but I will become level 11 on the 5th for this month, which is the final day of the event.
