During the quest "A means to an end" where you get to steal horses, my playerbar doesn't always turn into the "vehicle" health bar. My pet bar ends up being my health also, which is supposed to happen. However the main playerframe is supposed to change into the vehicle health bar, which it doesn't seem to in the case of stealing the horses. Anyone know where I should start looking to troubleshoot this?

It's on my warlock w/pet out while stealing the horse.
