Guild Wars 2

So I was 6/7 on my Minor of Enhancement Achievement, and I picked up the last one I needed (the slingshot) and it didn’t register. Anyone else have this issue?

EDIT: I found out what I’m missing actually, but its strange, I was 6/7 before the slingshot, but I know what I’m missing now to complete it.

And that was? (In case someone else gets the same bug/issue)?

Probably the wallet.
