Family means they are part of your enclave and have full trust. I don't know whether the limit is engine based or code based. A couple of things that also occured to me: Duplicate traits. Many characters have Trait.Voice.Playable specified, but they also get that as a subtrait of the main voice trait. They can be removed from the TraitBlock, but I don't know if it makes a difference. But, for cleaner code and the possibility it makes a difference, you could remove these. Some have Trait.Sandbox.StartingBackpack, but then have a backpack assigned in the inventory. You don't need the Trait.Sandbox.StartingBackpack if you are automatically giving them a backpack. Some jobs and hobbies are essentially the same in terms of effects... if you have a character who has two hobbies that give them the same effects (like Starting Cardio 2)... pick one and remove the other. That can save you a slot.
