Why would a Sim eyes change Color

Not going to report this as bug because there was so many factor could have done this at the time could changed my Asian Sim eyes from Dark Brown to Green

before the change.

world event holiday started, I name it Battle Royal. it's when sim beat each other up and hug after.

In the middle of this, I wanted to change my Sims outfit. (Rocky Moment) I put cheat code cas.fulleditmode (not thinking) and edit her in cas to change outfit and only change outfit. when I click finish and return to game play, I didn't notice it at first, but did later. I notice her eyes went from Dark Brown to Green (Sim: I want New Eye Color NOW, while we here) started thinking, bug? no. because no other sim has lost their eye color.

May-Be Sim Mom or Dad?. maybe, because Sim Mom eyes where Green at the time when I was making her in cas long time ago.( we are talking 2014 here) I did change her Green Eyes to Dark Brown then later having 2 kids with them. their eyes where Light Brown and cas edit them when they where children to have Dark Brown. now, Teens, they still have Dark Brown Eyes. until the other day when I cas edit my main sim (1 of the Teens) to change clothes then back to play when I notice her Eyes are Green (Crazy and Funny)

Well, either way I will keep her Eyes Green. she wanted them I guess

mods at the time

I ruled these out
