Projectiles do not register collision components if collision component is not set to root

Projectiles do not register collision components if collision is not set as the root of the actor in the components pane.

1. Create new project (first person template)
2. Open projectile blueprint
3. In components tab, switch collision and static mesh components so that the collision is the child component.
4. Compile
5. Press PIE and fire gun

Results:

Projectile will fall through the floor

Expected:

Projectiles bounce off of surfaces
