The recent "portable snowfall" aura cosmetic and the older "snowverload snowstormer" aura cosmetic currently work only if you do not have an aura active.
I suggest they be made into overrides, so you can enjoy them when using an aura.
This past winter I did quite a bit of skilling using auras, so was unable to enjoy the appearance of the new snowfall one while doing so.
Also, when the "festive" aura is used while you have one of the cosmetic auras active, you don't get the wintery wings. Maybe this can be dealt with as well.
