[The Alpha Bat]

Castle BDP battle map cameras are borked on the map with the pillar in the center.

On battle start, the camera for all players will be placed onto the center of the map right in the middle of the pillar, meaning you can only see the five stone pillars tiles and everything else is black.

The same issue as a spectator trying to watch a battle on one of those maps, no one can see what's going on.
