4.11 crash on save after duplicating keyframes in Matinee

Hi,

I’m having a lot of troubles with editing my matinee actor in unreal. When i open my project and the only thing i do is open the matinee, copy some keyframes, move them further down the timeline, close the matinee & then try to save the scene the project crashes during the save. It happens almost every time, but not with every camera group.

Anybody has any idea why this is happening? Seems like a bug, but can’t quite figure out what the culprit exactly is.

I also took a screen of the Crash Report
