Thanks in advanced for any help!

It appears to be any Blueprints with “Timeline” nodes in them

I have found it is the “Timeline” node causing problems, if I try to copy the Timeline node from one Blueprint to another I get an error of the similar type above

Hi cdrose,

Can you post your crash logs here? These can be found at \Unreal Projects\PROJECTNAME\saved\logs.

Hi ,

I’ve attached the Crash Logs in a here, this is when I try to copy a Timeline node from one Blueprint to another.

Thanks
