I've noticed this happen several games now. I will build an Eye of Rhianne and after a few uses it gets stuck in one spot and won't retarget (yes, I have sufficient power when this happens). Even if it is destroyed an another built it won't work. Other players in the game experience the same thing. I know some of the times its shared tech, but its happened at least once also where I was Aeon at start and it did this.
Is there something in FAF PvP that limits the use of this or is this a game bug?
