I played with it a little bit and it seems to happen in two cases:
a) log out was forced (my provider kindly delivered a disconnect while I was doing this, I assume server restart would work too)
b) you left the selected area while tool is on (entered a building or mine, ported to providence, etc.), can pm you a video for this one
