Weld disables itself

I am trying to build a ai tank, but for some reason the weldconstraints disables itself, then the head would just fall through the map.

How do i make it so that it doesn’t disable itself?
I also tried to constantly enable the welds, but it doesnt work.

Are you moving the Head at all? That will break the Weld and make the Humanoid die.
And instead of Weld Scripts why not just use WeldConstraints for all your Parts.

it won’t work if the one being welded is anchored which will anchor the holder

try unanchoring both of them

is all unanchored, the problem im having is that the head falls of the map.

it would look like this:

I removed the weld and just update model’s cframe constantly in a script.
