[Bug] joining Tol Barad or Wintergrasp

Hello:

I have difficulty getting into Tol Barad or Wintergrasp. When queued I get the prompt to join the battle but am never transported. When I get into the zone myself, I am repeatedly teleported to the exit side of the Tol Barad bridge and told I've exited the battleground. Similar results in Wintergrasp as I am repeatedly teleported out of the instance.

This is new behavior since the patch this morning
