Hi
I wasn’t able to reproduce this warning in 4.7.6. To test, I created a new Actor Blueprint with a Static Mesh component, and spawned it at Begin Play in Level Blueprint. I tried spawning same Actor on a Listen Server using Server’s Character BP, and that didn’t log a warning either.
Does this occur in a new project, or only your current project? Does this occur when spawning any type of Actor, or only a particular Actor? Can you provide some more details on Actor you are spawning? What method, and from where, are you spawning Actor? Any additional details, screenshots or a test project to help us reproduce this would be appreciated. Thanks!
