Alpha 10 Bug? Hearthlings sitting around fire and building

Is this a bug where the Hearthlings are just sitting around the fire at night and not working or eating? Also the Hearthlings building looks off and slow. Is that a bug as well? I have tried to restart and try new settlements and I get the same result. I was just wondering. In all the Alpha 10 looks great and it crashes with the building also but all in all works and looks great. Love the undead!
