I don't know what triggered this to happen but it happened around the time that the game had it's big recent update. Obviously I have no problem with the colour of the baby's skin but as this occured in my main game, it is a little irritating as it doesn't fit in with my family. I have the crib mod, but I've had it for years and this has never happened. If the baby is laying in there crib, untouched, they remain the unoriginal colour, but as soon as the baby is picked up, it changes back to the original given colour, then as soon as the are put back down, they change back to the unoriginal colour. I have tried many things and nothing has worked. If anyone could help me figure out this problem it would be so appreciated.
