no worries the obtained part is for making your dreamies, so in this case I would put all the villagers you want in your town, and the ones you already have will have a little 'obtained' pixel next to them. If you don't want that I can simply put the villagers you have now and change them later if you want new ones, without the obtained pixel.
I'm not available for the rest of tonight, I'm so sorry I couldn't get Tia to move out! I'm next available Thursday, or you could get her from someone else
