Reinsert PhysicsActor variable back into SOP.SubscribeForCollisionEvents() in order to avoid a race condition.
A separate PhysicsActor variable is used in case some other thread removes the PhysicsActor whilst this code is executing. If this is now impossible please revert - just adding this now whilst I remember. Also makes method comment into proper method doc.
