Spot battles broken

There's a problem since the start of the season that only happens in custom spot battles. 3 things can happen:

1 - Spectator’s camera goes crazy into the ground when watching some players (totally random as concerned to which player’s turn or which round).

2 - Black screens (sometimes it passes in-between rounds or when the spot battle ends, but you’ll have to miss part or even the whole battle on a black screen).

3 - UI freezes and you can’t move or quit the battle. Even when it ends, you still aren’t able to move, so you inevitably have to restart the game. Sorry if the comments sound a little too emphatic sometimes.
