I think the Meitou semibreve on the Persephone nastaya is bugged. it does not shoot when under ai control. I think it's missing ai hints or something
EDIT: I added a regular semibreve to the weapon group and it started shooting. checked the AI hints with TMI and the semibreve had a STRIKE tag. the meitou only had a SYSTEM. went to the weapon_data.csv file added STRIKE to the meitou and now it works as expected. DO_NOT_AIM might also be suitable since it's guided, but I don't know enough about starsector modding to gauge that.
EDIT 2: After seeing its performance in its current form, I'd say no. DO_NOT_AIM is not a good idea. it has about a 25% self-nuke rate as it is, do not aim would just make it nuke itself even more. If anyone is interested, it tends to nuke itself by firing a semibreve and then either turning in on it, nuking the nose, or the semibreve switches targets to a different ship off to the side and turns in on the hull of the persephone. But honestly, I think the fact that every single time I've lost this ship, it's been cause it nuked itself is kinda funny and based, so I absolutely love it.
