Hello Helghast , I have posted a question where I am having the same problem, the acter being referenced is a flag and whenever I move this actor around in the world it keeps spamming this exact message. IF you happen to have the time to look over my question, I would gladly appriciate it since it’s preventing me from working further in my project. I’m sending you the link to my question. Actor Crashing UE4 - Programming & Scripting - Unreal Engine Forums in the question I forgot to add this part of the output log.
