Child entities of a prefab in UEFN cannot be reliably manipulated when spawned

Summary

Summary:
Child entities of a prefab in UEFN cannot be reliably manipulated when the prefab is spawned. Movement and rotation consistently fail, while mesh visibility changes are inconsistent. Root entities of the prefab function correctly.

Issue Description:
Entities designated as the root of a prefab have expected functionality; movement, rotation, and mesh visibility changes are possible. However, attempting to manipulate child entities within the same prefab yields inconsistent results. Movement and rotation changes are never applied, while mesh visibility changes may or may not be applied.

Verse

Steps to Reproduce

Steps to Reproduce:

  1. Create a prefab with multiple entities, including a root entity and several child entities.
  2. Spawn the prefab into the world via verse device and make sure its attached to the simulation entity
  3. Attempt to move, rotate, or hide the mesh of the root entity via a custom component.
    • Prefab should be rotating and moving
  4. Observe that the root entity responds correctly.
  5. Attempt to move, rotate, or hide the mesh of a child entity via a custom component
  6. Observe that the child entity:
    • Does not respond to movement or rotation attempts
    • May or may not respond to mesh visibility changes

Expected Result

Expected Result:
Child entities of a prefab should respond to manipulation in the same way as the root entity.

Observed Result

Actual Result:
Child entities of a prefab do not respond consistently to manipulation. Movement and rotation changes fail, while mesh visibility changes are inconsistent.
