Not sure where to post this, have exact examples on the other PC.
Some of these dropped augs will sale for various amounts of Adventure Points at the boxes. The "box" will quote 2 Adventure points, for example, for an item, but more than once, I only received 1 point when I sold the item. Will get the exact examples, but from what I saw, there was no rhyme or reason as to why it was happening.
As example:
Ruby 1
Quoted - 2 Points
Sold - 1 Point
Ruby 2
Quoted - 2 Points
Sold - 2 Points
Ruby 1 (duplicate)
Quoted - 2 Points
Sold - 2 Points
Also, one just one occasion, I was quoted 2 points, but received nothing after selling back to the vendor.
