Hello,
I confirmed yesterday's legendary contest but got those mythic game orbs instead of Enna's shards on Hentai Heroes despite having just 50 of them. I though it's just visual bug but when I confirmed it the next contest changed so NOW I can win her in next contest. When I look at Nutaku's Harem Heroes, it's probably same - the reward is reported to be mythic game orbs instead of Enna's shards, and I'm at first place, and next contest reports I can't win her either!
