Pcg on demand not working on a packaged build

Hi,

I have a c++ project started in 5.2.1 ported to 5.4.4, where I also use pcg. Actor with pcg component also has a spline, actors need to generate within that spline. User can dynamically change locations of spline points and pcg needs to regenerate according to that. Pcg works perfectly in the editor, but not in a packaged game. Spline points reposition, regeneration is triggered, but pcg still takes in account the original location of the spline points, not updated one. It was same way in editor until I added node “Notify properties changed from blueprint”. Now with it, it works in the editor, but not in the package. Hope anyone can give me an advice on this. Thank you in advance.
