The Antorak Marauder of the Vasari faction has a skill, Phase Out Hull, which makes an enemy unit or structure invulnerable, but also disallows it from moving, phase jumping, using abilities, etcetera. The problem is that the auto-cast of this ability is not smart in the following case. Near the clean up phase of the game, after destroying an enemy colony, I had my ships destroy the remaining enemy orbital structures. It got to a point where all the units were attacking the last remaining structure, but the Antorak Marauders were phasing out the structure. In effect, it took a lot more time to destroy it than was necessary, since disabling the structure from doing anything only hindered the effort. Perhaps the logic for autocasting Phase Out Hull should be changed so that it isn't cast on useless planet structures or something? I'm pretty sure I was attacking a trade port or something, and there isn't much point to disabling that kind of structure.
