Hi,
Well In every single private server I have played in this has worked.
Well Lets Say Your hearthstone Has Run Out and You want to you use it again but have to wait 1 Hour -.-:
So Click On the Help Request tab( It's the tab where you make tickets for Gm)
Then You Will See Three tabs. First 1 Says : Talk To Gm
Second Says: Report Issue
Now The Third One Says: Character stuck. Now this 3rd one is supposed to port you back to your Hearthstone when you are stuck or dead, however You can use this and It Will Just Port You to your hearthstone. I have used it since patch 2.4.3 Till Now which is 3.2a
Enjoy
