Started a new real and a new character, I was fighting the first boss and noticed sometimes I would effectively parry but the sound and animation would not occur, I would get the focus form the parry and all but since there was no Parry sound and the visual effect that happens on a successful parry it would take me a second or so to realize that I had in fact done a parry. I think this also happened with other enemy npcs but I am not 100% certain right now.
oh forgot to add, I was using a claymore, I have not tried replicating this with other weapons.
