Issue: Not sure if it's a bug or working as intended, but, I'm getting poisoned through perfect blocks when fighting the Black Widow.  I'm at the point in the game where I've been farming them for the super venom.  Went to fight one this morning and after a flurry of attacks and perfect blocks I'm getting poisoned.  This was not happening before the patch.

Also getting stunned after some attacks that land successfully.  Never had that happen before today.  Not sure if that's because the poison stacking or a newly introduced but undocumented change.
 

Seems like a blocking related bug, not sure if there is a fix though.
