What steps will reproduce the problem?
1. I've created my own group called flying - only flying mounts have been selected
2. use /mount flying
3. The same mount is constantly selected even if it's not flying
4. If I summon a mount the normal way, log out and log in again, /mount flying will then constantly summon the last used mount - even if it's a ground mount not selected in the flying group.

What is the expected output? What do you see instead?
I would expect just a random flying mount to be selected but the /mount flying only summons the last used mount whether or not it's in the list

What version of the product are you using?
204

Do you have an error log of what happened?
no.

Please provide any additional information below.
I've had this problem for the past few version, I have to revert to 198 to getting be able to get a proper randomly summoned mount.
