Idk if this is a bug or not, but I closed and reopened my client, logged back in and went to do my Myoboku trial. After I hit 2 or 3 of the disks a message came up saying reward claiming in progress. Please try again later. Messed up the flow... It also didn't have 20 coupons on the side where the rewards are after I completed it. Maybe the reward claiming in progress thing made it so that I didn't get a reward for the disk I just hit off so even though I fully cleared it, it didn't give me coupons because it doesn't think I hit the last one even though I did and it said I beat it...
