Tech Support has issued an alert at the Wow Realm Status reporting Battlegrounds and Arenas are affected by a bug that make you unable to leave battlegrounds. Some of my guild members are currently stuck in Battlegrounds unable to leave. Make sure to update your guild’s message of the day alerting your members of this issue, or there won’t be raid tonight.
It is unknown when Blizzard will be able to resolve the problem. Keep an eye on Wow Realm Status forums and/or general forums for any updates on the situation.
Adidan: We are aware of the ongoing instability issues affecting the Battlegrounds and Arenas across certain realms. Due to this instability, players may find themselves unable to leave a Battleground after it has ended. This is something that we are working on correcting and will resolve as soon as possible.
We apologize for the inconvenience this has caused, and thank you for your understanding.
