m_TransformData.hierarchy == NULL and crash on Transform::CountNodesDeep after importing ARKit package from asset store

Scene Management


To reproduce:
1. Create new project
2. Import ARKit from the Asset Store
3. Open UnityParticlePainter scene
4. If Unity hasn't crashed yet, switch to the other scene

Expected: Switching between scenes is done without any crashes.
Actual: Unity crashes after switching scene.

Errors appear in console:
Failed to load component (MonoBehaviour)! Removing it!
Assertion failed: Assertion failed on expression: 'm_TransformData.hierarchy == NULL'

Note: On 2017.2.0b1 Unity crashed just after importing ARKit from the Asset Store. Just after importing ARKit and opening UnityParticlePainter scene Unity should crash.

Reproduced with: 2017.2.0a1, 2017.2.0b3
Not reproducible with: 5.6.2p4, 2017.1.0f3
Regression since 2017.2.0a1

Fixed in new ARKit package version 1.0.8
