I'm on the armstrong boss fight on hard mode and whenever I need to destroy the wreckage he throws at me I can't seem to aim my blade with my mouse. For some reason just moving the mouse to aim will trigger the blade to swing without me clicking mouse 1. Not only that but whenever the blade aimer is moving it's very slow and hard to control. On a side note I also have lost my ability to do the offensive defense move after the fight with sam.
