Some details :

(name) : Can contain the name, for exemple (Stone) Blocky speak about Blocky and Stone Blocky at once.
If you drop something I didn't listed on the list from one of the 4 zones, say me, I'll add it in the list with the mention *Not verified*, until I drop it myself ^^. Hope this will help you.
