No I’m not applying any movement.
I notice that when cars are moving under a low speed (20mph or 895 unit/s), this problem rarely happen since cars brake smoothly.
Should it be floating point precision, then the car with bike who follows splines and whose BP functions are written by myself should also have this problem. For now I’m thinking about the plugin issue, too but need more suggestions from the developer to debug.
For this post, I am wondering if this problem can be solved by modifying some properties of the collision box.
