Pandaria Falling through ground

[nikik101]

In Wetlands, near Slabchisel´s Survey there is one point, where I was walking and the whole world just dissapeared and I fall through it. Twice. So.. be careful where your steps are going.

You should consider reporting them on the Bugtracker.
In addition to that, you can always use the Unstuck feature on the web if your character cannot be revived in-game.
