So I have done every single mission in the game both Faith's and Jacobs regions completely done yet in John's region it still says 51/52, I have done the YES sign mission as well as all of the hidden cache missions........when I defeated John I believe I may have had the mission Hit the gas not done at the time then it was marked as completed after beating John and I am thinking it may have glitched out and did not get added into my 52 total............
It's Ubisoft. What did you expect? Wildlands was so buggy in the achievements, I'd gotten the one for unlocking all of the rebel perks while I've yet to unlock the one for getting the first perk. Jeez, do they even bother anymore? I guess they aren't when they can count on sales regardless of their games' gameplay, story or pretty much anything else.
Huge disappointment.
