The logic makes sense as the villagers do jump around to fixing huts if they have some building, fishing or crops if they have some farming even though they may be checked for research. However I am seriously thankful it is only that one because I dread to think of how many villagers I would have right now if all the ones who have some parenting skill did the same thing.
I have played all the VV games over the years and I have to say this is the only time I have ever had something like that happen. I'm going to try VV2 on this Vista and see what happens to that one. I've been playing VV3, VV4 and VF on this computer without any issues so will experiment. Thank you for your thoughts on this.
