[Bug] [0.915] Oddity fighting against curse, using the defense ability.

Was playing here to test  through the last parts of 0.915 before you patch it up, and was fighting a darkling shaman who cursed my hero repeadetly.

I noticed that if I was cursed, and then used the "defend" option. I would end up at 5 defense while defending (no shields or nothing).
But if I was defending, and a curse hit me, I would go to 0 defense while defending.

Ok im a bit lazy atm. so youll get a screenie from mr dropbox.

Sincerely
