Missing spline mesh component in packaged project

Missing spline mesh component in packaged project, in editor and standalone works right, but after package missed.
Help, please. Video for clarity: Spline mesh bug - YouTube

Best regards, Alex.

I am writing this for the voter. Crutch solution is creating spline mesh component on begin play. But this is completely inconvenient, because designer сonvenient to set up level OnConstruction(), before game started. Waiting answer from Epic.

Crutch #2.



TArray < USplineMeshComponent* > SplineMeshArr;

class.cpp in OnConstruction:

USplineMeshComponent* MeshComp = NewObject(this);
