I don’t know if it’s a bug or not….but with a friend (party of two) we did the “Don’t break the shinny” mini-dungeon…there’s only one person that can break the shinny which is what trigger the achievement….but only that person received the achievement…we had to do it twice then …
Shouldn’t the whole party have receive the achievement on the first run ?
Not that it is really hard of anything, but annoying since it’s called “mini-dungeon”.
