Did you follow the readme and run the .bat command will in game?
Yes, I did. Extracted everything into /fallout3/data-folder, copied kids.txt to /fallout3-folder.
Typed bat kids in the console, (several times) and it seemed to work. Went to kill some children in the little place Republic of Dave in the north east of the map. But nope, not even a 1 inch head shot(or several) kill them, they just stand there or run around. =(
Thanks anyway, for trying to help! I don't know i there are any other ways to solve this though.
