Physics Constraint - Edit red bounding box?

I have a door that is set up with Amnesia: The Dark Descent style physics - the player can grab the door and move it using a physics handle. It works perfectly when the door is freestanding. When I place my curved door into the curved archway, however, the physics freak out and it either flies away or jitters and gets stuck in a wall.

I feel like the red physics constraint bounding box might be the reason why? My door is curved, not square, and I’ve only ever seen examples with square doors. Is there a way to edit the red bounding box, or is there a better way to do this entirely?

So! I fixed it myself and it was a really stupid thing…

My archway didn’t have custom collision, just the default one Unreal generated when I imported it. The hole of the archway wasn’t open and it was colliding with the door.

Leaving this up for search purposes - check your object’s collisions!
