overlap events do not fire when collision components such as sphere or capsule collision components are added to a vehicle blueprint. Overlap events seem to register if the component overlaps with other components of the same blueprint, however overlapping with other objects returns nothing.

Steps to Reproduce

1. Open Editor (vehicle project)
2. Open sedan blueprint
3. Create sphere collision component, move it to the front of the car and resize so that it will easily hit objects in front of it.
4. In event graph, create a component begin overlap of the collision component with a print string (any text) attached to the execution pin.
5. compile
6. Press PIE
7. Drive vehicle into objects that will overlap the sphere collision.


No print string occurs, overlap event never fires


Overlap event fires, string is printed to screen.
