Reproduced 3/3 times. Issue also occurs in //UE5/Release-5.0 - CL 20979098 Binary. Not a Regression.

Steps to Reproduce
  1. Create a new BP Blank Project with Content Samples
  2. Create new Character Blueprint
  3. Open new Character Blueprint
    1. Click on Mesh (CharacterMesh0) in Components
    2. In Details Panel, add SK_Mannequin as the Skeletal Mesh Asset
  4. Open SK_Mannequin_PhysicsAsset, and change the Physics Type of all bones on one limb (e.g. Right Arm) to Simulated.
  5. Create an animation blueprint for SK_Mannequin.  
    1. Search and add a RigidBody node, and in Details set Simulation Space to World Space
    2. Search and add a Jog_Fwd node, and in Details set Loop Animation to True
    3. Connect Jog_Fwd to RigidBody, and RigidBody to Output Pose. There will be Local To Component/Component to Local conversion nodes added automatically.
  6. Compile all changes, and add two instances of your Character Blueprint to a new Level
    1. In the Details Panel, set the Anim Class of both instances to your new Animation Blueprint
  7. Scale one of your instances to 4, 4, 4
  8. PIE

Actual Result: The upscaled character will have the simulated limb stay the same size and appeared shrinked compared to the rest of the body.

Expected Result: The upscaled character should have the simulated limb scaled with the rest of the body as usual
