Help with custom trait plz: The Arrogant Trait

So I found a custom trait on mod the sims by Just Kizzy which is perfect for the story I'm trying to play out in game with a narcissistic sim however the trait is out of date and causing a LE in my game.

Just Kizzy doesn't seem to be active anywhere that I can find for support (if anyone is aware of where I can find them please advise)

Alternatively I am wondering if there are any modders who would be willing to take a look at it for me and see if they can fix it?

There are no TOU. Here is the link to the info:

Any help would be appreciated. TY
