When moves over the Actor set after PrePhysics( e.g. DuringPhysics ), the bone with the physics enabled will stretch.

Instead of directly using PhysicsAsset, using RigidBody nodes does not cause this issue (even if it is set to WorldSpace).Also, this issue does not occur if you disable tick of the floor.

Steps to Reproduce
  1. Create a floor with tick group set to During Physics (Activate the tick event so that Tick runs)
  2. Characters that some bones move by physics walk on the floor.


  1. Open attached repro proj.
  2. Walk on TestActor

result : The bone is extended (delayed?)
