With the NW weekly of Orb Vallis conservation going on, I went to go work on it. As my main is Nezha, experience in PoE has shown me that I shouldn't try to call for pickups of tranq'd animals while having Warding Halo running. (It'd be nice to not have Warding Halo kill tranq'd animals, of course, too.) I melee to get out of conservation mode and pop into my Operator to actually go over to the animal. Once I've called it in, though, I get a white, semi-transparent overlay that is persistent on my screen until I head back to Fortuna.

It's not game-breaking, at all, just annoying. I haven't seen if it's the case in PoE with the current update, but it wasn't a problem there last week.
