Male Alien Pregnancies from abductions not possible anymore?

@PugLove888Both times I had 7 sims in the household and no other sim was pregnant (the first time I was able to invite another sim to the join the household after I gave up on the abduction baby).  Both times the 8th sim died and that was when I was trying to get a sim abducted so he would have an alien baby.  I have looked around and I see others confirm their sims were abducted and got pregnant from it.    I'm just really confused.  I see other people say it took 3 or 4 tries.  I'm on 10th try and nothing.  Like it can't be bad luck, and the final 2 I had the MCCCC mod with 100 percent rate.  So something must be broken right?  I have MCCC and the book of chaos mod. 

I guess the book of chaos mod is the problem because that is how I'm getting the sim abducted.  I believe the mod is using the alien abduction debug cheat, so perhaps sims won't get pregnant with the debug mode cheat.  I assumed it would work the same because I've seen let's plays where people use the mod for alien abduction pregnancy and it works.  Maybe that was years ago and EA changed the debug cheat.

Another guess on my part is I haven't tried putting the sim in science career or had the particular sim use the telescope to look for the truth.  Honestly after setting MCC chance to 100% I didn't think anything else would matter.

Is there a specific time?  I've mostly tried at night between 9pm and 6am.  Maybe there is like a 10 minute window or something that I missed?

Thanks for the replies.
