Physical and invisible hitbox

I suspect that i have a corrupted prefab. But i just wantet to check the subreddit just incase.

There is a physical and invisible hitbox jetting out the side of my prefab. (Visible with the blue selection grid in the picture) Players won't collide with it, but all other physics do.

Peculiarly. Neither box nor connection mode ignores this invisible hitbox regardless of how you select it..

However.. Strangely, placing other vehicles inside of this invisible hitbox includes that new vehicle when saved as a new prefab. regardless of how it's selected.

I have also double checked if the invisible hitbox is originating from world spawn.. Yet again, no dice...

If not a corrupted save, it is most likely collision calculation quirks with microbricks. But i hope for neither as finding that microbrick would be like finding a needle in a haystack!

Any help is appreciated. Thanks!
