...Although, as one of my ladies just reminded me today, it is possible (and maybe even common?) for newborns to get crushed/suffocate to death due to falling to the bottom of the pile, since asf's like to huddle, especially when young. So probably a good idea to separate them right before your ladies pop, or you end up with some dead babies.
So far I know for sure I lost 2 (momma was eating one, found other on bottom of pile, fed that one to my ferrets), and I think the stress of my rapid removal of the first litter/moving the adults out temporarily because they were bitey today/ spot cleaning tank because it was empty anyways/etc may mean I lost most of her litter this time around. saw a bunch of them looking like they weren't breathing, going to wait a few hours and check again/see what's left *sigh*. Atleast I noticed before my other lady started to pop, so shouldn't be a huge loss.
