Nostalrius Begins - Quality wow vanilla realm (1.12)

I tried to walk across the mountains near the charred vale, but ended up getting stuck in a valley between mountains. I am not glitch stuck, but can't get out. I tried using the hearthstone, but it says that spell is not ready, even though I hadn't used it for several hours. Is there any way out?

Try opening an in-game ticket using the "Help" > "Stuck" selection and ask a GM to teleport your character out of where you are stuck.

thanks! worked out fine
