@cravas: thank you for the enlightening link!
Both work on 11.1 A9LH+Luma 6.1.2 (normal).
I was able to visit both cities via online.
I use ACNLs JPN and USA (this is RF) and description files in /luma/locales for them.Maybe a specific situation, but anyone running A9lh with luma region changed sysnand know if it's safe to update? I assume it is since it's not much different, but I don't have a hard mod so don't want to test yet.
