Female teen sims can't age up?

@igazor Removed all the CC for a test and was able to age up without problems - so its definitely that. Good to know! But I'll have to weed out what's bad, but I'm not quite sure where to start (I do have a decent amount).... do you have any idea or educated guess to where I should start? The weird thing is I tested aging up in a brand new Sunset Valley save - and the first time I tried it, with CC still installed, Master Controller still reset all the Sim's sliders to zero. So somehow some CC I had must be interacting with Master Controller in some way? It's very weird.

@Turjan I don't use any custom body or facial mods! It's all very weird. But I'll double check again in case there is one installed somehow without my knowing.
