You're welcome! But.... I've since found out I might actually be wrong. I've seen this POI in other towns on our map, with different numbers on the building's roof sign. I'm guessing the name that appears on the danger meter might be the POI's "filename," while each location the POI appears in will differ based on the roof's sign? Kind of like how in real life if a city has multiple fire stations, they'll be designated "Station 5, Station 6, etc."
If I did actually find a mistake, I'm glad I could help!
