Tweening Motor6D breaks prismatic constraint

In another project i am using both IK and a Motor6D to create movement of an object.

I’ve made an example place showcasing my issue of the motor6d’s effect on a prismatic constraint,
the attached part sometimes does not update and stays static in the tween and IK movement.

I have absolutely no clue on how to fix this, any help would be appreciated!
