Spline collision not updating

I’m trying to make a spline during runtime that the user can interact with. I can make the spline in the editor and everything works, the collision deforms and I can get a hit test on it.

But when I spawn the actor during run time and set it’s end points, the spline mesh deforms, but not the collision. The collision stays at the scene root where the actor is spawned.

Is there any way to get the collision to deform with a spline that is spawned during runtime? I need the user to be able to click on it and get a hit result.
