We are aware of the ongoing instability issues affecting the Battlegrounds and Arenas across realms. Due to this instability, players might end up being unable to leave a Battleground after it ended.
This is something that we are working on correcting and will resolve as soon as we possibly can.

We apologize for the inconvenience caused, and thank you for your understanding.

If any updates are available, we will notify you through the proper channels.
