Ever since I downloaded the latest patch I have been unable to perform finishing moves on Sirens and Ekhidnas. A prompt will appear above the enemy saying "Finish Off", but either nothing happens or I simply do a normal attack. The finisher works fine on Harpies, however. I recently upgraded to the GOTY edition and the problem persists as well. Is this an issue for anyone else as well? I know this is only a minor problem, but is there any fix?
