Hey @mokucat789! Welcome to the forums!
It… doesn’t really make sense to have a door be a physics object when it just slides down. Nor to have a physics object go into anything. They’re doing what they’re supposed to: if there are overlaps of collision and it’s a physics object, the farther it goes in before it’s released, the harder it will rubber-band back out.
Physics objects can’t be jammed into other physical things… they will just end up shooting the other direction, or falling through never to be seen again.
Hope that helps!
