Honestly, what the hell. Unless you have some special little feature already to disable exotics, which i doubt given the fact that it didnt work for the older set, you would have to go into the game and turn it off manually. Why cant this be done with eververse? Hell, you could even just disable it all together even for people who have an item and it would be a better fix. But instead we get a constant eververse right in our face in the tower. Really nice with the timing how its most likely going to go away once the dawning is over. TLDR; it cant be that hard of a fix. Just like every other programmer in the world, you back track what you added in until you find the issue. And once you find that spot that causes it, you fix it. And sometimes that means disabling a feature all together until its working again.
