Procedural spline mesh generated based on the path finding and nav mesh data does not show up in the packaged game!

Splines are generated in the construction script procedurally using position data from “Find path to location synchronously”. It works perfectly fine in the editor or standalone game but is missing in the “packaged game”

I have already turned on “Allow client side navigation” in the project settings but still no luck.

Any hint on what might be wrong is appreciated !

This was fixed in 4.19
