I think most of you missed the part where even if you know how to solve it, all it takes is one idiot in the area randomly clicking to screw it up.
If this was something in a story area so it was just yourself or your group, it would be much better. Out in the open it is one of the most annoying missions ever, and one I tried to complete once, but will never bother with again.
I will freely admit, that's a very good point. My playtime is generally very late at night/early morning, so I usually don't have to worry about morons wandering through and spoiling my fun.
