Re. MC Command Center, these are the reported issues, according to @Deaderpool:
Changing outfits for things like going to bed, exercising...anything that the Sim does a Spin to change the outfit really, is causing an issue. EA changed the function I use in my scripting to determine what outfits to use, especially around MC Woohoo settings.
The Sim Picker Dialogs I display will be broken. So that means any MCCC command that opens a dialog to choose a Sim will throw an error. This includes starting pregnancy, probably MC Commands, setting relationships between Sims, etc.
