If you scanned a villager but also invited someone else to your town...

on the same day, but only had 1 free plot left, who would move in? The amiibo villager you scanned or the villager you invited from another town?

I believe that the last invite overwrites the first, but since there's amiibo involved I'm not 100% sure...

I didn't even know that it was possible. I just assumed if you invited someone anyone else wouldn't be able to move to your town.

Well, if there's was only 9 villagers when you invited someone from another town, it might count as 10 when you scanned an amiibo in, you'd get the option to kick someone out, I think.
But I'm not sure, good question.
