Lunar deviations exclusive question

OK, so I’ve been grinding out the deviations to get all of them, and I’ve been looking everywhere online and I haven’t found anything about it yet now I haven’t seen a snowsprite in one of my manibis chests just yet, but I’m hoping somebody would have an answer for me, do we know if the snowsprite/lonewolf are still server exclusive to their respective servers? Or have I just been unlucky? Again, been looking for an answer and hopefully somebody has one for me. (asking as a frost player)
