How to reproduce:
1. Open the attached “IN-138602.zip” Project
2. Open the “SampleScene”
3. Enter Play Mode

Actual result: “transform.localScale = Vector3.zero” throws a “NaN” value
Expected result: “transform.localScale = Vector3.zero” shows 0 as the value

Reproducible with: 6000.0.72f1, 6000.3.12f1, 6000.4.1f1, 6000.5.0b2, 6000.6.0a2
