These are the bugs I found so far.

Area's:


Tabacal:
- Side Misson : Medication Raid - When you steal the helicopter the nav marker does not update on where you need to turn it over to the rebels.


Media Luna:
- Kingslayer Files - It says 9/10 When I have explored and collected all of them in this area. (I can confirm other people have this aswell)


Weapon Attachments:


Scopes:
- EXPS & G33 - Sometimes the magnifier is in front of the scope when it is at 1x zoom.
- Micro T-1 & G33 - Sometimes the magnifier is in front of the scope when it is at 1x zoom.
- RUS Red Dot & G33 - Sometimes the magnifier is in front of the scope when it is at 1x zoom.
- G28 - When you are aiming with 5x the scope is not aligned. (I don't know if this is intentional on this scope)
