Thank you for the report!
I've seen screenshots around the forum showcasing how Frigades and other ships consider most fighter LPCs as actual enemy ships and will engage them instead of the "real" enemies.
Hmm - frigates might at times, but other ships generally speaking don't, not if there's anything else around.
The AI in 0.95 seems to consider even just fighters and bombers (that have already spent their limted Ordnance) as a bigger threat than actual enemy ships (which have their weapon in range). Here's a straightforward example of a Conquest aiming its 90° omni shield at some Lux Heavy Fighters (which are just offscreen) instead of the Radiant sitting in front of it, despite both the ship orientation and the weapons aiming (and firing) at the Radiant:
I've currently only got this one screenshot neatly showcasing the behaviour, but I'll provide you with more as soon as I get back to playing!
Just gave this a try and not seeing this kind of behavior here. There was a bug prior to RC15 that caused the AI to do this for Piranha bombers specifically, but that was a very isolated/specific bug, not general to fighters, and should be fixed at any rate. What would really help is a vanilla setup in the simulator where this behavior can be reliably observed.
This *could* potentially be caused by a modded weapon, for example, btw - for example, something like the vanilla Bomb Bay but without the BOMB tag.
(Let me move this to the modded section, actually - this could well be a vanilla issue, but generally speaking things go there if the game is being run with mods unless there's *near complete* certainty that it's a vanilla issue. Or unless the mods are limited to, like, console commands.)
