As others have mentioned, this is a really fun idea but the mechanics are very much not intuitive. My main issue has been with linking hexes, I was eventually able to get the cause of death button to show up after some confusion but I have found myself completely unable to get the search records button to show up when linking the digital archives, high school, and year. I feel like I have tried them in every possible order (as well as both zoomed out and zoomed in as I saw others mention not being able to get it to work unless they were zoomed in) and nothing I do seems to work. I don't think there's anything else I can do to make any progress without this so I guess I'm stuck there unfortunately.
