Not really a bug I guess bit just and idea.
I am building a little robot in Pawn Class BP.
Importing from Blender 2.81.
I am in Unreal 4.24.1.
I just had to reposition my components (different objects) in Blender and re-import them into UE4.
I made the simple box collisions inside Unreal 4.
I just notice when you reposition the pivot point of components in a Pawn Class BP the meshes adjust if you re-import them which works fine but the collisions you made
in the static mesh editor are still in the old positions (old pivot point for each component).
It would be be nice just to re-import them and the collisions “know how to adjust”
Just a thought
