After mines are finished with their amazing physics upon placement, they are forever bolted into that location. This normally doesnt apply to gameplay, but two times when this happens is: 1) placing mines on walls. I bet turrets work just as fine. 2) placing mines on map sided buildables. A minor thing surely, however its quite awesome to have a (escort 3rd flag) 9 mine that doesnt go off right away and you can fish for that vehicular multikill. Im not adamant about it, but im pretty sure even if the driver(or as im led to believe, anyone in the tank) has defuse, a dude in the turret can still trigger them. Awesome. Still, you probably want to fix it. Sometime.
