[Bug] Jump Pad and Mine haywire

This bug is very weird, and I have been able to reproduce it everytime I try. I was on the blood eagle team on Isle when I first found it. If you arm the mine (have it selected) and aim it so it is at the base of the Jump pad, the jump pad starts going haywire. By this I mean that it starts pumping up and down like it senses someone around it.
This happens on anymap that has the jump pad, but I first found it on the Isle maps. The key to reproducing it always it placing your reticle at the base of the Jump Pad (as shown in the scrennie). When you have aimed the mine at the base of the Jump Pad, the pad starts going crazy. If you do not have the mine activated, this bug stops.

Both screenshots show exactly where to aim the mouse (reticle) to get the bug to show itself.

Maybe the jump pad has some kind of phobia?

Nice catch.

That's really weird. Award for the Strangest Bug of the Day.
