After browsing through the code, I found that the current best method is to just reattach the collision component to it’s parent component like so.

This will cause the USceneComponent::UpdateOverlaps() function to be called.
Note that “Attach Type” is “Keep World Position” and “Weld Simulated Bodies” is is checked.
With that said, this seems like a bug and should probably be something that could be addressed when spawning an actor. I’ll look into writing a fix for this and making a pull request.
