So yeah, there’s a bug a bunch of friend and i are experiencing with the event. When we complete a lap on the board game, we see the rare chest poping on the screen but it never show up in our loot. So everytime we do a lap, in the end we get no reward at all. For now, i only got 5 rare chests out of 8. Its really annoying.
Also, a similar bug can be see when you complete 3 mini-game objective to get the normal chest while lvling up a hero at the very same time. You only get 1 chest. I lost with that 1 epic chest and 1 Valeera or Brightwing (i dont remember exactly) loot chest
