Description

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.

Steps to Reproduce

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.
