I gave that a cursory glance and thought it was for saving my personal version of the web map to track the progress that I had marked off.
Now, my brain is even more boggled, though. I tracked down every chest. Multiple times over the past few days, I sat under the blue crystal contemplating my life choices. Never once did the chest tracker make a peep.
I got within sight of it (after uploading my save file... Thank you) and my chest tracker was blowing up. I have no idea how the last few days are possible because that chest can apparently be detected from half of that area. I know I had R toggled on.
Anyway. That sucked. On to the DLCs :)
Thanks.
