u/Neighborhood-Gold

I’m attempting to 100% the game but I’m stuck at uncovering 100% of the map, I’m at 99.1% and for the life of me I can’t figure out where I haven’t been. Every collectible has been found and all other trophies have been achieved. Has anyone run into a similar issue? If so what was your solution? Google hasn’t been much help, any help would be appreciated.
