An odd fall damage glitch.

Hello friends!
My name is Harmiton, longtime PC/Console gamer and game community enthusiast. :)
This is my first time creating a thread so I am a little nervous.
So with this I apologize in advance if I missspell or type in something that can be missunderstod or unreadable.

So lets gett to the subject.
I belive I might have stumbled upon some sort of glitch while I was online playing on my level 20 Warrior in Ogrimmar.
In The Drag of Ogrimmar close to where Gotri's Traveling Gear is one can find big steel tablets on the ground. It is there on those tablets I experienced this odd moment.
I was riding by on my Wolf when my character suddenly stops and falls to the ground.
Not more then a second later the Floating Combat Text tell me I gott hit 10 times for 101 damage, a closer look in the Combat Log showed me that it was Fall Damage that cause it.

Now I know that I did not run my Wolf down the side and gott damage that way this thing that happend to me happend when I was riding on top of the tablets that is lying on the road.
Might there be anyone that has experienced this odd thing when adventuring around Azeroth or Outland?

This is the first time something like this has happend when I could not figure it out, so I fellt that maybe I could help out in someway by doing a Thread about it should something similar pop up again for someone else.

I would just like to end this with my warm thanks to the creaters, developers and caretakers of World of Warcraft for making and maintaining this amazing game that even after six years of playing it I still find this game fun everytime I play.

So thank you everyone for taking the time to read my first thread.
I hoped it was not to much of a bother and hopefully it did help in someway. :)
