Archmage, if you are referring to the latest version of Village Sim Editor, it's not dangerous. I have used it up until v1.1 is out.

I hardly use it except for conducting breeding experiments. I wanna see if a male and a female who were masters in say Farming and Breeding, will have offsprings that are at least Trainee Farmers as soon as they are born. But I was disappointed.

Now VSE and VST don't support v1.1, so no more experiment for me. Anyway, good job, Brett! You made my day!
