Issue with vehicle bugging out when running game

I found a model of a bus, and I customized it to make it look how I wanted. When I went to run the game, the bus flew into the air as the wheels glitched, as seen in the video bellow. Does anyone know why this is happening? If you need more information about anything to help me solve this please let me know. I am not very experienced with using spring constraints and attachments.

We need to see what controls the wheels to know whats the problem, and you should probably move this to #help-and-feedback:building-support as well.

Okay so how do I move it there?

Try topic controls, I myself have not made a topic
