Guild Wars 2

Coming with the last update, I was happy to find a brand new copy of an exotic item (a mecha anchor) I had stored in the bank the week before. I am 100% sure the second one wasn’t a legit drop since I don’t drop exo nearly enough to forget if I got twice the same drop in a single week.
Now, I’m all for gifts, but I seriously doubt it was intended. So, what do I do with it? Can I keep it, or should I destroy it?

If you suspect it was due a bug or something, try to contact them through support and they will get it sorted.
