More Awesome Than You!

Yes, I know under ordinary circumstances zombies cannot be made pregnant, but something very interesting has happened to me.
My sim had just woohooed and gotten pregnant, then met an untimely demise mere hours later.  A generation later, I resurrected her as a zombie, and after a day her belly got bigger!  A pregnant zombie, still carrying the baby of her husband who died long ago of natural causes... remarkable!

I'm just curious as to whether this will actually work.  Will my sim still be able to give birth even though she's not supposed to be fertile?  I don't want to go through with the birth if it's going to cause a problem with my game, so I figure it's better to ask if anyone has something like this happen.
It does give me some hope though, since her LTW of "Graduate Three Children" can be fulfilled, she has one child that is still a teen, and birthing twins would give her three she needs.

Yes, the birth will go as normal.  However, she will not be able to get pregnant again.

I guess you'd better start feeding her cheesecake.   :P

Or change her lifetime want with the lot debugger.

Or use the twins cheat.
