Wield, dual wield and a necromancer bug.

I don't have any logs sorry, I rarely log, and I died before I save one. I'll try and explain this simply: I'm a Duergar Warrior with full strength. I'm wielding a random heavy weapon. I'm dual wielding a mace of earth. I try to wield a blacksmith hammer (the iron one from Balator), and I get the echo "a hammer is to light to be wielded whilst dual wielding a mace of earth". I remove the mace. I wield the hammer. I dual wield the mace. Very annoying when disarmed as I have to remove mace, wield hammer, dual mace instead of just wielding the hammer again. The other bug was when I was ranking with a necromancer. I was in the room with him asleep and saw the echo for his blindness (not sure if failed or not) as he cast it on the mob.
