[BUG] Hearthstone not teleporting to the right place?

Don't really know where to post this other than here. So basically I joined a group via RDF and got placed in The Scarlet Halls. But when we were teleported, there was nothing there and when we moved we fell through the world. Respawning didn't help, because (at least for me) we were in the same nothingness when we were teleported in the dungeon. I left the group, Alt+F4, as I couldn't log out, went to the Warmane site and used the char unstuck service. And I was teleported to my hearthstone (which was bound to Silvermoon), but I couldn't move and all I could see is The Dark Portal from Hellfire Peninsula, though I could hear the Silvermoon music. If needed I can provide a video/photos of what I can see now. The 'loss' of this char isn't really a huge deal as it wasn't high level, but none the less it's quite annoying and I don't want anyone else to be in the position i'm currently at.
