I'm Level 5. I've unlocked Assault Rifles I (1pt) Sights I (1pt) Suppressors I (2pt) =4pts. I have 1pt to spend now.
I'd like to buy Sights II, but it is not available to unlock. The path seems to show that I can just go down the tree from the attachments.
What am I doing wrong. The only things showing that I can unlock next are Machine Guns I (2pts), Smoke Grenades (1pt), Assault Rifles II (2pts) and Vests I (6pts).
Why can't I unlock Sights II, it is the next in the path and I've unlocked both Sights and Suppressors in Tier I?
What must I unlock in order to unlock Sights II?
Thanks.
