The Average Gamer writes: "If you see someone else mining a wall, you can pitch in and join them with the collaborate button. Work will go faster and instead of earning three labour points per section, you’ll earn four. Great! But you only see your fellow players when they’re doing an action – cutting a tree, mining an island, picking up an item and so on. As soon as you’re done mining out a segment, your buddy will vanish and you’re left staring helplessly around until you see them mining nearby. This makes it very difficult to collaborate on more than the odd bit here and there."
