REOPENED NOTES:
Crash Reporter:
[Link Removed]
Test Project:
[Link Removed]
Open project and press Play: Editor will crash.
User reports this being due to sequential animations not being the same length and that removing Anim notifies will prevent the crash.
PREVIOUSLY REPORTED NOTES:
Adding a notify or notify state in Persona causes the editor to immediately crash.

1. In the shared project, press Play and wait a vert short while - it will crash.
2. Deleting AnimNotifies from animations = no more crashes.
3. Replacing animation2 (30 frames) with animation3 (20 frames, same as animation1) = also no more crashes.
4. More instructions inside the project.
Expected results: for shared file not to crash within 1 minute of opening.
