The macro to quickly exit a dungeon /click HelpFrameCharacterStuckStuck stopped working on Tuesday. What should I use now for mount runs?
See: https://wow.gamepedia.com/API_Stuck
For your second question, see specifically the Details section, bullet point 2.
Thanks for the link. Am I able to call that Stuck() function from a macro or addon? Going through the UI has large loading times, seems to file a support ticket and ends up taking multiple minutes to port me out.
It is the function that was called when your previous macro “clicked” the button.
It can only be called by Blizzard code ().
