ever since get famous my sims are obsessed with the mirror arghhh

@carlymichelle, I'm not sure if there is a mod specifically for mirrors, but MCCC lets you disable any autonomy on objects that you want. It allows you to turn off specifically by the object type and specific interaction, rather than just the object type as a whole even. Very useful.
That is probably the main reason I use it.

@soko37, Pretty sure the answer is no.. I seem to recall clicking a celebrity and being disappointed that the menu choice for using MCCC's autonomous editing feature didn't show up. I assume, because it's a Sim, not an object.
