Instanced Static Mesh components created through the Construction Script aren't visible in Standalone Game. Collision is still present. They are visible in all other play modes and if created on Event Begin Play the issue doesn't occur.
This is a regression:
Working in 4.16.3-3561208
Not working in 4.17.0-3573198
It shows the mesh in all the other view modes and in the editor but not when playing in standalone. It works in 4.16.3
Blueprint is using the [Add Instance node] with an [instanced static mesh] imputed into Target and just a change in Transform.
Results: The Instanced Static Mesh component will not be rendered during that play mode
