Say you're trading a villager for a villager with someone, and you get your villager you want to trade with in boxes, then the recipient claims them. Then, if you TT to the next day when the plot should be empty, is it possible that it can be filled up by a new villager instantly, say, from someone's void? Just curious about this, since I will be doing this hypothetical situation soon and I don't want that end result to happen. Thanks!
In my experience, the day after boxes is usually a grace period - the plot should be empty. That’s when I burn through my NMTs to find a dreamy. However if I don’t find anyone I like and leave it vacant, then the the plot will definitely be filled by a random villager the next day.
