I've had a few instances of characters changing names without me doing it:

-in the first instance, one of my female characters took on the same name as a male character (i changed the female's name so i wouldn't confuse them)
-next, the previously mentioned male took on the name of another male character...i left them the same to try and watch for it to happen again, but it didn't
-then a blonde female child named Soda was born (just thought it was funny that her name was soda, lol), later i discovered and older female child's name had also been changed to Soda
-the next time i looked i had two other young females (making a total of four) named Soda

In the instance of the guy who was a duplicated twice, on the details screen he was sandwiched between the two of them (ordered by age).

With the 'Sodas' the original Soda was like 3 people away from the 2nd Soda, but the 3rd & 4th Sodas were right after the 2nd one, respectively...

Anyone seen this before? What's up with that?
