World bounds and out of world actors issue

We have a bug, when some times physical actors fall through the ground and keep falling indefinitely after an hour or so dynamic aabb’s boundaries are overflown and physic simulation is no longer working.
Solution for this would be to use MBP broadphase algorithm and world bounds, however it’s performance is worse than SAP’s and we’d like to avoid it due to consoles.
Is there any other way to implement world bounds with SAP?

You could try putting a plane underneath your world to catch the falling bodies, or you could make it act as a trigger and destroy the actor when it hits it.
