Vehicle bug

OK, first off. 13.0 bug. If you equip a vehicle, suddenly you can not interact with things in any way outside the vehicle, like spells, rightclicking the grid mahcines and things like that. Secondly, if you want to step out so that youcan interact, youfind out that is impossible. When I equip the car, it turns invisible until I close and reopen the window. When I unequip it, it disappears again, I close and reopen window, and the vehicle is still equipped. I fould no way to unequip it. I guess running through a zone would do that, at the moment I was not close to one, so I had to log out, and then relog back in again. Just thought I would open this forum with that small problem.
