Still breaking ??? ... :scared:

That may mean that the body parts are not "weld"ed to each other. :huh: ___ Huh?

In other words, the original mesh did not have the vertexes in adjacent body parts (objects) in exactly the same locations. :huh: ___ Huh?

You may need to go back and look at how you created the original mesh ...

Was it created from a single mesh?  :blink:
... And, then "group"ed to create the separate body parts? :blink:

... And, then, using the Grouping Tool, use the
Spawn Props" function to produce the individual body parts before creating the figure? :blink:

Just a few thoughts for you to consider.
