I too fail to see the purpose of these chests. Nevermind that they seem to be bugged right now and that may annoy some people. But why even add them? Is it the sole purpose that ‘people love opening chests’? Because if it is, then this is not a success. They are mostly annoying, you can miss them and they do not really add the ‘chest’ feeling. You do not really need that when killing mobs, looting the corpses was fine, better than this. It is simply an extra buttonclick that adds nothing, just draws away from the experience. They are indeed hard to spot and, since they actually are suppose to contain that valuable loot that you are after, just stresses you out. Ok, you tried it, it did not enhance the gameplay, actually the opposite. My vote is to remove them.
