Yet another way to get into Old Ironforge which I have not yet come across on MMOwned; have searched, but can't find this method anywhere, apologies in advance if this is a repost!

(too noobish to post link, please replace * with a dot)
1.Follow the directions on the vid.
2.Once in the end location, face directly towards the top-middle of the vault, as close as possible to it, then blink up or use auto-unstuck (with HS deleted obvs).
3.You'll find yourself on top of the vault!
4. Walk West, to the edge of the vault roof, put up some freefall,(Noggen/Levi/Whatever) and jump in a North-Westerly direction.
5. When you fall into Old IF, remember to quickly cancel your freefall so you dont boil in the lava
-Notes-
-> I'm pretty sure, though not certain, that this is a Gnome only exploit because of hitbox size, to initally get into the end location of the vid.
-> When on top of the vault, if you jump forward, you can land on the top of the throne in the Kings Room.
-> Jumping to the east, missing the Kings room chucks you down some huge abyss under Dun Morogh.
-> If you have a GnomeLock, or any other inferior Warlock, they can set up a summoning stone 'on' the vault, and you can summon people up on to the top of the vault, once the resourceful gnome is on top, by making a summoning portal there (you can click the portal from below)
-> This is on a Live Server during patch 3.1.3
-> Enjoy!
