Really interesting stuff. Rockstar nuked the GTA Forums and Reddit where a lot of pieces were being put together. There was a map thought to be previously debunked that now lines up with some of the leaks. Basically this map but not sure if I can link to it because it includes some leaks.
Yeah that one. Here is the post of someone breaking down the map and how the current leaks matches a previously debunked map. It's not a perfect fit though.
Trying to process it all as it has been rapid. This map was debunked a year ago, but now matches a little tp what was leaked to some extent. Think of the rdr2 map that was leaked years early which was 75% accurate. The GTA Forums has for decades been piecing together maps of these games. It was stopped for the moment but will likely resume again.
