Stuck in Attack, Welt4 (German)

Hey! Unfortunately this is an ongoing issue. We are working on it but it turned out to be more complicated than just simply restarting worlds. You can read more about the issue in my answer marked as solution here: Stuck on "Attack in progress" error after September 18 | EA Forums - 4967413

We will inform everyone as soon as we have found a solution. Thank you for your patience!
