This has probably already been asked elsewhere, but I can’t find it. My profile/avatar is still showing ACNL, even though I no longer have it. I haven’t been able to figure out how to change that to ACNH. When I tried deleting my old town, from ACNL, I get a message saying that I can’t because I have residents. However, when I checked, it says there are NO residents listed. This is very confusing.

Hey there!  Make sure under the “My Characters” section you have your character(s) removed from the town that you are looking to delete.

You can change your avatar by going to your profile and clicking on it.
