To reproduce:

1. Open the attached project (ParticleSystemLateUpdateBug.zip)
2. Open the Test Scene
3. Enter Play mode
4. Observe that particles aren't visible in the Game view but are clearly in front of the camera in the Scene view

Expected: the particles are visible in the Game view
Actual: parent's scale is changed in the Update and then changed back in the LateUpdate, but child Particle System doesn't react to the change made in Late Update. It is in the right place in the Scene view, but is not visible in the Game view and even focusing on the Particle System object focuses the camera on empty space meaning that internally Particle System's position is different than the visual one (the visual position is correct, but actual position is not).
