Glitched to Fall Apart, Looking For Reasons?

uploaded by XantrX 11 months ago

Hello everyone, Last night I made a small differential, and it worked perfectly every time i spawned it in. Today loading in the same one, it falls apart every time. Ive tried to make new ones but none of them work, they keep falling apart. Anybody have any advice?
