Sure it's a Generator in the Financial District? My "Signal" also don't react anymore, so i guess i collected everything.
Any "tiny bits" that are well hidden? I found the gas station under the bridge, i also checked the "X and Y"-Map Markers for that one, but every propaganda-car, every gas station, every statue and also every collectable was found (?). Also on the Skyscrapers the Detector is quiet.
Residential District is finished too now, it was a Baby Panay-Statue in some "Forest" of the City. So lets focus on the financial one.
In the Financial district, or a similar city, I didn't have 100% yet and could never find that missing item. One day I was F'ing around killing Heat on the highway and we stopped, had a gun battle, and right next to the highway was a little water tower. Shot it up and got my 100%. This was purely a random and somewhat maddening event.
Statue, gas/petrol station, water tank, electric transformer, propaganda wagon.. you could missed something. Also climb every roof top as well as look under the bridge just in case you missed one parts/armor box. --- After series of bad lucks, there is always good luck follows. - Syuji Terayama.
Whats the name of this site? Im having the same problems with the Park District. Im sure I have all the Statues, Prop. trailers, petrol stations and caches.... well pretty sure. And fly above the city, there are no water towers left. Checked near the elevated highway- above and below it - nada. And in the surrounding islands - were there is only one statue and 2 + 1 caches hidden on a hill-site.
Still one thing missing as Ive got 100%, but no tick.
