We're aware that some players are stuck on the loading screen at around 39% and are unable to access the game.
We're currently rolling out a fix for this issue, however it'll take a few hours for it to go live.
In the meantime please do not use Beast Wars Ram Horn in battle, otherwise you will get locked out of the game. Thanks for your patience!
Update: The fix is now live, please restart the game. We will also extend the weekend event by 24 hours.
