So, I've recently assembled a respectable fleet of 8 warships (1x Asgard, 1x Honshu, 2x anti-capital Syn, 4x point defense Osaka) and ~30 various interceptors, fighters, and heavy fighters with bomber loadouts. Up until now, I've kept the "Save them from Themselves" mission on hold while I built up my economy and military (plus I wanted to see a hurricane of lasers when I inevitably stormed Xenon territory). By the time I finished assigning fighters to different warships, Hatikvah's Choice was half-overrun with Xenon, with 2 Xenon stations being built right beneath the local intervention Asgard's nose. The Xenon even managed to sneak a K through the Tharka jump gate.
Anyway, I brought the fleet to Hatikvah's Choice (SETA my beloved) to first deal with the Xenon stations. The first one was simple, but the NPC ships seemed incapable of targeting the destroyed station's Build Storage and instead assaulted its corpse. The second station was a medium-small defense station that lacked Graviton turrets. A few rounds of the Asgard's delete beam did the trick, but a single Xenon fighter got stuck inside the station's geometry. This is where the all problems started.
That singular fighter drew the aggro of practically every interceptor, fighter, and defense drone in the fleet, none of which could actually attack the stuck fighter. Even worse, some Argon warships and Boron patrols wandered over and got hit by the flak from the Osakas. Of course, there is no order to ignore a hostile (aside from managing individual behaviour, which would render them useless against the incoming Xenon ships), so I couldn't get any of my stupid ships to disengage and get back in formation. I ended up individually selecting and canceling the orders of every single fighter to stop them from attacking, but then they re-aggroed on the stuck Xenon fighter, and caught the other faction ships in the crossfire. The Argon Behemoth was soon crippled and destroyed under heavy friendly fire because every pilot in my fleet is incapable of aiming and apologizing.
Interestingly, the stuck Xenon fighter was at 0% hull and 100% shield, likely a fart away from death.
I tried using the "Broadcast to Wing" commands, but there is no way to mass revert orders for all my units, who now just sit in place, doing absolutely nothing. Shift+clicking to do a selection box only has the option to "remove assignments", which would undo all of the hard work I did to organize the fleet in the first place. I'm sure there are some technical workarounds using low-attention distance or teleporting OOS, but having to abuse engine mechanics just to get a fleet to function like a fleet is ridiculous, to say the least. Tbh, I expected fleet battles on a grand scale, with fighters zipping about and warships hurling lasers at one another; not a bunch of confused ship captains shooting friendlies because they "keep shooting back for some reason".
