After 1.19 released, multiple vehicle problems have surfaced for me. The first one is in manually shifted transmissions. If you do not "slowly" change gears, sometimes the server will believe your still in a lower gear and will over rev the engine which will cause it to prematurely destroy the engine.

Second is vehicles cannot climb hills easily anymore. Just trying to get back up the hill out of Zelengorsk forced me to shift the transmission back and forth from second gear to third gear, then back to second gear. If I didn't do this just right, it would cause the first bug where the transmission will stay in the wrong gear. Video's here: http://video.xboxdvr.com/gamer/wizardo3/video/166736572

Last, vehicle traction is absolutely nonexistent. All vehicles seem to slip and slide at all times, even when parked. I lost two cars to the vehicle sliding down a hill and ruining themselves against the environment. A red Gunther slipped down from where I parked it and into a river. And another slide ever so slowly into a tree and instantly destroyed the gas tank.
While no video's are available for those instances, I have another example with the truck once again. Video here:

I would also like to ask why the new Humvee parts are spawning in sheds?
