Tried to get past bug by creating Division from button when you select Clan Brawl (now it's active for us) . . now stuck in Division of 1, so can't enter a battle, restarting doesn't fix it. Game is now totally unplayable. Also, there's no way I can find of creating a player support ticket that doesn't run you round in circles.
Why didn't you just roll back on Friday as soon as you realised it was broken???
