There appears to be a loss in precision when moving instanced static mesh components.

Quote from licensee:

"...the ISM/HISM Components: In various cases UInstancedStaticMeshComponent::UpdateInstanceTransform() is called e.g. when moving the instance. In this function the local transform of PerInstanceSMData is rewritten with a loss of precision."

Steps to Reproduce
  1. Download attached project
  2. Open project
  3. Move the actor "Testactor" along the x axis

Result: The two instance static meshes become slightly separated
Expected: The two instance static meshes would retain the same relative distance when being moved.
