Disabling other players added items.

So many people playing this game do not realise, or perhaps are doing it on purpose, that you can infact disable someone else's added items, so, the person that added them can still use them. I have had so many games, where I add some items to form a line or addition to the world, only to respond, and find that some cretin has deleted them. Fair enough if you dont want to use them, understandable, but please, just disable them, instead of deleting them. It is infuriating in some instances.
