WotLK Can't use mount in cities

[babbygrills]

Every time I try to use my mount my mechanostrider(I only have one mount) in a city, I have tried stormwind and Ironforge, it immediately unmounts. It never gives me an error. I have no problems anywhere else in the game.

It is a bug caused by WoD/Legion models which affects gnome class mount while in a big city.
You can delete WoD/Legion models to solve the issue:
1. Open WoW folder
2. Open the Data folder.
3. Delete the patch-w.mpq file.
4. Delete the patch-x.mpq file
5. Open the enUS folder.
6. Delete the patch-enUS-w.mpq file.
7. Delete the patch-enUS-x.mpq file
