Hey Ben-
You said the code provided is called when the actor is spawned. Does that mean that you are calling this code in BeginPlay? What are the values of the variables used in your code? How are you calculating/setting ForceDirection, ForceToUse, PrimitiveComponent, etc.? If you’re able to reproduce this behavior in a new project, please include the setup steps to help me test the issue locally and/or provide the sample project so that I can see the results you’re getting directly.
