I think I have deleted your FC on my first 3DS as this 3DS has 99 people who I can't delete (Yes I'm serious) so I have to delete & readd each time I have trade that takes place there. But sometimes I forget to do so. So if you can see my gates, go ahead and unload your turnips!
Sorry for the delay, I was taking a bath. Looks like they haven't finished yet so I can't add you while opening gates, but once they're done I'll add you and open gates again.
