With all EPs installed the game will spawn something like 50 service Sims and there's nothing that I know of to prevent this. Same with the Aliens and pets, unless you uninstall Seasons and Pets. With AwesomeMod the paparazzi, however, should only spawn if there are any celebrities in town.
50 service Sims, just like that, in a world emptied of community/residential lots!?
I definitely recall seeing 2 paparazzi among the ones I saw and also a policeman - and I don't have any celebrities >scratches head< something must be off here, then. But what?
