[AA] Lil monster only got 1 trait/formal outfit removed

Could you please provide the following information

• Are you using mods/cc in your game ? Please remove them and test without them if you do.
• Do you know which outfit the game assigned ? Does it show up if you don't get CAS ? Could it be from a pack you don't own ?

I'm not using mods or CC. My mod folder is empty.

I've taken a few screenshots. Not sure what the outfit is called. It looks kinda like a recolour of the holiday pack outfits but made blue/orange.
They wear it fine before going into cas. After cas its gone for good.

The game also removes out formal outfit without going into cas if you turn the game off. Once coming back into it, the outfit is gone.

The problem isn't save file specific either. I started a new save file to get the screenshots. Its always 1 trait missing and the same formal outfit assigned each time.

Thank you for the details
