Just used two in a game, and they worked phenomenally. They flew from my main planet to a moon the enemy was on. It was a commander-interplanetary-nuke-snipe. However the strategic icon for the nuke didn't follow the actual path the nuke took. The strategic icon appeared way in the corner of the system, apparently just in the middle of space, and just stayed there. It didn't represent the true location of the nuke between bodies.
It was working before the camera updates. We are having similar issues with other things in space as well.
agreed, not just nukes but every orbital unit seems to change position when switching from planet to planet
