Naxxramas RP what goes on with the 80's

[IDK]

Hi, having not played on Naxxramas since 2020 I went on there and although a very small player count, almost all are level 80 but none are in Northrend. In fact some of the places they appear to be are unique, non standard areas such as Programmers Isle, Nine, Unknown, The Cemetery, or unique specific areas of Human starting area. What gives?
