This is a high priority bug that we’ve been trying to fix for quite a while. It’s still occurring, but we’ve made some tweaks to make it less disruptive to your testing while we figure out a true, permanent fix: going forward if it gets stuck on your character now, it should fade after 60 seconds.
However, if you already had it stuck on your character, it likely won’t be retroactively removed by this fix, since the hidden aura is already applied to your character. Queuing for arenas can remove it, since that forces some aura refreshes.
Alternatively, because I know this visual effect is obnoxious and distracting, I can try to remove it manually myself, but I make no guarantees about it. If you want me to try, you can post the following information here and I’ll try to handle it over the next day or so.
