PS4 disc version

Hi so ive progressed just passed norra saltholmen headed north and ive coverd most of the map before this.Ive just discoverd a mission entering the border warboard minken bunker destroy machines in south.This is the only mission ive discoverd since covering norra saltholmen even tho ive been picking up letters and discovering the daimond markers in this location.Everything i discoverd letters or daimond marked in this location hasnt opend up or continued the story.I beleive ive lost a mission or two wich one being the discover the bases warboards naval bases?or ones that hasnt even opend in between.I had a problem were the hp5 would not appear on screen for use and only when i tried to drop the wepon the game crashed with an error but luckily upon reloading game nothing was lost and the hp5 was playable.This is as far as ive got so far.If anyone else would like to add feel free thank you.This game has great potentiol ive dropped destiny for this lol just needs reports to be fixed in areas.

Just to make myself more clear ive picked up missions from Bjorknasskogen to Sodra Saltholmen.When i opend up safehouses in norra it stopped saying that ive discovered on screen proggress but i can travel to the safehouses on map
