Can someone help me with a Bug?

[TreeCore]

This doesn't seem to be an urgent bug. I run a gnome warrior named Zimnaryba. The issue seems to be centered around an unpainted mechnostrider.

I cannot seem to mount while in Ironforge. Also, I was mounted when I logged into Stormwind. I couldn't get past the front gates, couldn't get into the griffon roost, and couldn't see my character. I tried hearthing, and I could see myself as soon as I dismounted.

The bugtracker page didn't load for me, and I heard something about how I have to have a certain number of posts before I could use it.

I'll try having my geek get me a fresh download.
