Stuck on "Attack in progress"

Thanks for reporting! We are currently working on fixing this bug. Please not that this can take until next week. Thank you for your patience. 

I have the same problem with two bases when I attack the same forgotten camp and I can't attack or move my best bases.

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 know what's going on. :)
