A crash occurs when Opening a level with a Particle System that contains a warmup time and a Light module with High Quality Lights checked.
This crash seems very isolated and specific as it does not occur if you do any of the following.
1. Download and Open attached project.
2. Disable 'Realtime' in the Viewport.
3. File > Open Level > testMap (save if prompted).
4. Repeat step 3
Outcome Editor crashes
Expected No crash occurs
