Character gets stuck under the Stormwind Bridge

[laria]

My character was trying to hand in http://www.wowhead.com/quest=1685 , Gakin's Summons in Stormwind,Gakins Beschw?rung in german.
I'm not sure wether the SW Mesh has a problem or its the quest itself, but it walked below the SW bridge and got stuck there.
Hopefully the attached Log will help to find out whats wrong

Its possible that you have an old mesh, I was told the warlock trainer had been fixed.

Try making a new maps folder, if it doesn't work just restore the old one.

It's WoW giving a terrible location. Add a questing override yourself.
