Clearing their orders is a common occurance on non-simultaneous. Here's what happens. You order the ship to warp out a warp point on the far side of the black hole system (to get somewhere you want to be). The ship exhausts it's movement points AT THE WARP POINT INSIDE THE BLACK HOLE SYSTEM. If you look at it's orders (the little eyeball icon) it says only one thing -- WARP. Next turn, before it can move, the system's abilities pulls it 2 spaces in. Now it tries to execute it's orders -- and can't so it does nothing. I don't know if this is a more common problem on simultaneous.

Basically, you have to keep an eye on your ships in black hole systems. This will happen sometimes, and preventing it isn't really easy.

Maybe if you tell the ship to MOVE TO a sector past the warp point where you want to be warp wont appear in the orders list, but maybe not -- but I think still if it stops at the inside warp point, this still happens.
