We are aware of and actively investigating an issue where players may encounter an error that immediately terminates their game session on the PTR.
While we have attempted some resolutions, at this time, this issue is currently ongoing. We are continuing to investigate alternative resolutions and will provide additional updates in this thread as they become available.
If you encounter this issue and want to provide a report, we ask that you post your experience in this thread and refrain from creating a new thread. This will help keep our forum free of clutter for other feedback.
Thank you, as always, for your diligent testing and your patience while we work to resolve this issue.
