Creating stacked warp points

[Panarch]

I just tried putting a warp point on a black hole. First, I generated a warp point on a star, then I collapsed the star to a black hole. The warp point stays in 6, 6 and works normally.

The only difficulty I can see is if you exit the warp point and don't have enough movement remaining to get two spaces away from the warp point. If you don't, the black hole will suck your ship in and destroy it.

Hope this helps.
