Most likelly and ID problem with an AI submarine, as the AI subs are clones of the player subs, and pack3d doesn't clone certain nodes, your hydrophone shares the same identifier with the AI sub, and as the AI sub are drawn first, when you click on the hidrophone to move it, you're actually moving the AI sub hydrophone

, I'll try to fix that for the next patch, although I can't give any release date, as it's a big and complicated job.
