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 Adam,

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

Thanks
