Have not been able to enter Undermine since this patch went live. Game crashes when zoning in and get error WOW51900322. Am able to play all other zones and content, but have tested with multiple characters since o5/06 and the game crashes still whenever trying to enter Undermine either through the Rocket Rail or the Dornogal portal with any character.
Now I have a bunch of unplayable characters that are stuck in Undermine
