I've tried to download my expansion packs, before updating, and it doesn't let me. So, you're going to have to patch first.
I really love the new veggie options, and that you no longer need a trait to get them. It's something, I, as a vegetarian am very happy about, but roll my eyes at the same time, thinking, "Why didn't they just do this for the Base Game patch?" Now, I'm just gonna make my veggie chefs, by having them cook only the vegetarian alternatives, and just call them veggie. You really don't need a trait for this sort of thing.
