New sequence that had been saved.
Had 7 timing Timing tracks only for words for 7 faces.
Had broken down some phases.
Went to add the models from the views drop-down list. Selected Lepperton 2015 and system crashes.
Report attached.
So to be clear I had started a new sequence with timing tracks only. When I went to add some models it crashed.
Repeatable every time.
Cheers
