Hadn't played with vanilla ship systems in a while but trying out 0.97 stuff I noticed that this old bug is still present.
-When NPC ships with a ship system using Maneuvering Jets AI reach an order location (like a waypoint), they continuously spam their ship system even when not moving, activating them as soon as cooldown is up no matter what. Aside from being buggy and weird looking, it causes ships to not have the system up when they need it (i.e it's now on cooldown as torpedo bombers are approaching). Steps to reproduce is simply going into battle with any related ship, putting down a waypoint for them, and watching them constantly trigger their jets even when completely immobile on the point.
