Is there any way to either SM destroy or via normal game methods, get rid of sensor buoy type missiles? I ran a test where I fired one at a way point that was under the maximum range. Now the missile sits at it's target location and neither dies on it's own nor runs out of fuel. For a year or more now I keep getting interrupts saying "1x Size 1 Decoy Buoy cannot find its target. It will home on the previous target location and use onboard sensors to search for a new target".
I can't seem to select them with SM and also can't seem to target them with a ship to blow up, have I missed something or will they die off eventually? If so what sort of time frame?
