I've been playing far cry 4 up until now without incident. Yes a little buggy at times but what new game isn't nowadays. However I have run into an issue where my progression for lost letters has been lost. I picked up my 8th letter today only to see a pop up on the screen tell me it was only my 3rd. Now this will become an issue for me as I am a completionist and without getting this progression I can no longer get 100% I have recently just finished assassins creed 4 and even doing the companion app just so I can get the 100% For that game. I am playing on xbox 1 and my gamer tag is KILTEDXSCOTSMAN.
Have you ever played in online mode? It sounds like you experienced the save game corruption discussed here:

This happened to me and the only solution was to restart and lose 15 hours of progress. It has been reported on both PC and PS4 already.
