Child transform's position not updated as parent moves

I have a parent game object Object1. It has a child, which is simply an empty game object called ReferencePoint. ReferencePoint can be any arbitrary point on Object1 itself.

I have another game object Object2. It has a public field called RotationReference, of type Transform. In the inspector, the ReferencePoint on Object1 is assigned to the RotationReference field on Object2.

As Object1 moves, I expect ReferencePoint to change its position as well. Object2 is supposed to change its rotation to face its RotationReference -- in this case, the ReferencePoint on Object1:

Code (csharp):

1.  
2.     public override void Rotate()
3.     {
4.         Vector3 relativeRotationReferencePosition =
5.             this.RotationReference.position - this.transform.position;
6.        
7.         this.transform.rotation = Quaternion.LookRotation(relativeRotationReferencePosition);
8.     }
9.  

However, I noticed that Object2 is not rotating at all, even when Object1 is moving. When I step through the call stack multiple times, I discover that this.RotationReference.position always has the same value, even though Object1 is moving.

What am I missing here?

 

How often do you call Rotate()?

 

Maybe localPosition

That looks like it would work to me, might be worth changing 'RotationReference' to a gameObject and using RotationReference.transform just to make sure it's definitely getting the right values.

If you want to upload a basic scene with the problem visible I can have a look.
