I used to teach myself to always use an attack in move, now it looks like I need to disaccustom myself to do it

At first glance this looks an awful lot like https://github.com/ZeroK-RTS/Zero-K/issues/4200 , but that issue seems specific with [cannon] weapons, scorcher is [lasercannon]. I think the screenshot you have is not the whole picture, some projectiles cleared past the factory(admitedly it looks like less than 50% passed the factory). I think this is most related to the slight inacuracy of scorcher, and some fuzzy elmo rounding errors. For these straight shooting weapons isn't there a way to take into account the inaccuracy of the weapon when detecting a clear line of fire?
