Nah, I've been watching closely the last few hours, picking shrooms (got 907 so far!) while I wait for the mac release of VV2 !!!
I have been closely monitoring the population count and I noticed that my child count increased by 1 just as soon as my population decreased by 1 without showing any body.

That leads me to believe that there definitively might be a failsafe prventing nursing mothers from dying while nursing, and that the corpse does not appear due to the time elapsed between the time she should have died and the time she released the child.

Maybe one of the games developer can let me know if this is so?
