One of the reward slots in Team Battlegrounds is empty

There are only three rewards per level in the Team Battleground Blitz. They are unlocked when:

- one Team member conquers the Battleground;

- two Team members conquer the Battleground;

- four Team members conquer the Battleground.

There is no reward for the three members conquering the Battleground. The third slot is just for displaying the Team's progress.
