Model deletes itself when the game runs

Hello, I am trying to make a trailer for a semi truck. However whenever I add a hinge constraint when I run the game the trailer just deletes itself.


Even weirder is it works if the parts are massless or have a density below 0.1 (however in this form its so light that the truck does not act as it should when you drive it and the trailer swings too much) so going of that i have tried to fiddle with the weight but the only thing that did was make a trailer that vibrated so much it jumped into the sky. I have also went searching but found nothing relating to my problem.
What am I doing wrong here?

I guess the constraint is not attached to the part of the trailer… Or some bug maybe not sure… But yeah.

I think it flings with super speed into void and gets deleted but Idk what you can do to fix it

Run the game through ‘Run’ mode, it will show you more precisely what is happening due to there being no loading screen.

Idk if you did this or not but try and anchor the trailer that usually works for me.

I‘m guessing that the trailer is a mesh part? If so; maybe the mesh hasn‘t fully loaded and you need to wait a little longer for it to load?

Meshes shouldn’t unload when you click Play since there is no reason for this to happen since it’s already loaded.

Anchoring won’t help him since that will disable the joint.

Could it have to do with the constrait’s parent not being orientated properly, causing for some ‘flinging’ which makes the trailer appear gone?

I didn’t think of that lol. Thank you for correcting me.

when i put it to massless the wheels where oriented correctly

I solved it by tweaking only one of the parts mass and setting the rest to massless instead of adding weight to all of the parts. Thank you too everyone who contributed! For some reason this works but im still unsure of why.
