I hope I'm not doubling-up on this topic, but couldn't find it anywhere. When someone appears at my home once they have visited me, I click on them visit them back in return. A gift box appears but I can't open it. It used to be we could receive extra gifts (above the daily 9) if we visited back someone who had visited us. I'm not sure my Avitar stays at neighbors when I've visited them so they can revisit back. Does anyone have any info about this? Thank you.
