Description of Bug Experienced:
After mounting my cavalier's summoned mount and obtaining +46% movement speed, upon teleporting to a new server, be it through lens or portal, I get to keep my movement speed buff permanently on foot.
Steps to reproduce the Bug:
1) Summon Cavalier's custom horse
2) Mount on said horse
3) Teleport to a different server (lens or portal)
4) Dismount horse
5) Teleport back to original server
Expected Result:
Keep the movement speed buff if mounted (which does not happen, interestingly enough) and/or lose the movement buff if not mounted.
Actual Result:
Player maintains the permanent movement speed buff indefinitely, on foot.

Additional Information/Notes
I do my best not to abuse this bug and avoid it, however... it happens quite often on essentially every session I play.
Also, in order to fix this effect, both to lose or re-obtain the movement speed, depending on the current scenario, all one needs to do is mount & dismount (or vice-versa).
