Strange Client-Side Vehicle Behavior When Touched

[dthecoolest]

It looks like a NAN error similar to this other tank problem.

And my one:

Vector3 values become NAN after period of time

So I got this weird problem and I don’t even know where to start with debugging. After around 30 seconds of staying still with my mech, it just goes poof then the legs permanently go away. I can confirm this only happens when the mech stays still because I was able to ride around for 40+ seconds seen in the video Any thoughts on what’s causing the issue and how I can debug it? If it helps the animation is done by CFraming the legs client-sided.

I would suggest looking into all CFrame math operations, Vector3 stuff, and importantly humanoid related scripts for the issue.
