I complete mission without monster of gift

Third consecutive week that I complete the mission and it does not give me the monster, is a mistake of my game, which it is possible to do?

If you’ve already won a prize this season, you’d be in pool B. If you’re in pool B and completing the missions this late after they come out, then chances are likely that no more prizes remain to be won.

Unfortunately they have glitch Cryst, I had never won prize since the start of season 2, there have been few times I finished an hour after, still didn’t get the prize…

Some people played way after me still got the prizes…
