I'm also having the problem with Reset not working. The RunCode solution works for me, but it is a pain. Any update on when Reset can be fixed?
I'm using WOTLK version.
I've noticed this same problem. Character lands out of range of the node. Since node isn't in range, so he just mounts up and leaves.
For me, I notice it about 10% of the time and I think it seems to be on the same nodes. Sorry I don't have logs or anything right now, I was just browsing the forums and noticed this.
