it would be nice to have some kind of way to prevent people from automatically restoring gardens/trees/rocks/etc. when they crap out. sometimes i'm waiting for something to croak and then someone comes along and restores it and then i have to shell out 2k or more in currants for wine of the dead to be rid of it. (on top of feeling bad that whoever wasted their time/energy/resources/well-meaning-ness on it too.)
even if you leave a note/note pole, some don't always read it first (i've been guilty of this myself!) or they ignore it because they want the img or whatever.
i'd suggest having a "let me start this first" type option maybe? where if i come home and see project available, as the owner of the house, *i* click restore, and then it's open to everyone. (or, i delete the thing.) people who like things the way they are can just stick to "let anyone restore this" or something.
perhaps also keyholders can be exceptions.
