i have allow more than 8 sims in a house hold set to true but when it apparentally doesnt count to other households because i wanted to do a risky woohoo with my sim's girlfriend but in the debug it says she has too many sims in her houshold and im wandering is it suppose to only work on your active household?

There are six different mods that allow for overstuffed (Greater Than Eight). Many of us have all of them anyway, some of course do not, but they all do different things. MasterController's setting, for example, only applies to MasterController commands such as Add Sim, Instant Baby, and Pollinate. It has nothing to do with making babies through woohooing, you need Woohooer for that.

Regardless of how a household of more than 8 is formed, you also need StoryProgression for an inactive overstuffed one to stay together.

The parts each of the different mods play are explained here:
