We are experiencing numerous front end crashes that we believe to be caused by a host issue. We are working on resolving it quickly but we will be needing to work on the late war arena resulting in multiple arena resets today. We apologize for the inconvenience and thank you for your patience. This is a really odd problem that blindsided us on what should was a very minor patch. It requires a larger number of people to trigger which is why we didn't see it prior to release and why it's only showing up in the late war arena. We hope to have it fixed very soon.
