After the most recent update, I am seeing this at a specific location on the map. It's not tied to any of my quests, as far as I know. It's visible from pretty much anywhere on the map, but gets larger the closer I get. Any idea what it is or how to get rid of it?

Is there any other location that I could download the A17 version from? I've tried on a few different browsers with no luck.
