Expected behavior

basically i was making my own car. after a bunch of collisions or accelerating(all physics). it will disappear. every part. i tried a free model(the f1 in the image) and it also happens. i’m new to developing, please help me.

The issue is happening in this part of the code.
Comment those lines and that’s pretty much.
Also, please delete this report as it’s not bug at roblox end and there’s your discord webhook leaked
