I've played this before on my desktop computer that has Windows XP. I decided last week to put it on this Vista and try it again after reading others playing it. It does seem to run a lot by itself in order to get the tech points up there and I have to say VV4 is still my favorite with all it's action. However, twice now there is this one female who has been carrying a baby when I check back in on the game. I actually checked in on it because I thought I would need to add another child to reach my 25 so I was shocked to discover I already had 25 and this female was carrying again. Parenting has not and is not checked on her so I have no idea what is up with her. In fact none of the villagers are checked for parenting. Any ideas?
