Hello, yesterday I added some assets to my game and enabled them, they were police and fire department vehicles and some truck and when I tried them out, every time they would move their wheels wouldn't spin like they should and wouldn't stay in place as seen in the images and the video. Some of them are working normally but some aren't.
