Ensure when adding more than one camera to world in VR mode

Ensure when adding more than one camera to world in VR mode

Description

Ensure condition failed: Lhs.CurrentNum == Lhs.InitialNum [Link Removed] [Line: 197] Array has changed during ranged-for iteration!

Ensure occurs after dragging in multiple cameras into the world in VR mode.

Previously dragging in cameras caused a crash (UE-45574) in 4.16 and 4.16.1.

Steps to Reproduce

Setup:
Have access to QAGame
Have access to a VR headset and controllers

Repro:

  1. Open QAGame
  2. Enable VR Mode
  3. Navigate to the Modes Panel and click on the Cinematic tab
  4. Drag two Cine Camera Actors into the world (if this doesn't cause the ensure then drag in another)
