In the top bar, the green “achievements” number shows +14. But when I open the dropdown, I see four items totalling +20. Why does the total not match the sum of the items?
No lower entries were highlighted.
This post was deleted (by you), resulting in a net -16.
Just like your profile, we don't show changes due to deleted posts in the achievements dropdown. They are however available in your profile if you opt to see them via the checkbox at the bottom of the reputation tab.
