I've been playing Far Cry 4 for a while but have got to the point where I'm not being offered any further missions and can't progress. For the whole of south Kyrat; I've found every location and lost letter, destroyed every propaganda poster and Mask of Yalung but can't progress any further.
Is there something I need to do to get to the north? I'm assuming I need the Key to the North mission to be offered to me?
It seems that this is a bug introduced by one of the patches. I've discovered a couple of other references to this during searches and they follow a similar pattern: Two or three of the Shangri-La and or Reggie and Yogi missions have been done but the game stats don't register these.
There are a couple of mentions of people getting round the bug by visiting the Shangri-La mission locations but this didn't work for me. In the end I had to restart the game, losing 30+ hours of game play.
