2h Sword + Shield!

Issue/Problem/Bug:
You can apparently use a 2h sword with an NX shield.

Describe the problem. Be as specific as possible!:
Tried out ~2 years ago. Shouldn't have been fixed, as there aren't many who notice this issue:

• Equip shield.
  
• Equip NX shield.
  
• Blow up shield.
  
• Equip 2h sword.

Wait. Brilliant idea. I want to try this with a polearm.

Hmm, shoulda tested it out with PA. I think it's going to work, however not at all animations. Mine occured only at special attack-animations and whenever I was alert (breathing) as you see.
