Recently republished my missions after the latest January patch - my NPC ships still didn't move so I created a test mission and fiddled with the wander settings.
The ships moved! Slightly. They seemed to move for 1 second and stop and then not move again for ages. So it might just be a question of finding the right settings? Either that, or the default settings changed from the Dec 22 patch and are set too low because the ships just appear to be static when you just leave it at the default settings.
So I guess wander mode works (sort of), but maybe raise the default settings? I hope other people who have said they have a problem with this will try changing the settings to see if it starts working?
EDIT: I've tried a variety of settings including medium on every setting, maximum on every setting and I can't get any consistent ship movement results They mostly just sit around idle.
Are there any recommended settings somewhere? Or is this thing actually broken and NPCs aren't responding to the settings given?
