Can you post that method? Else, according to ServUO code, the only way that happens if attacker is null, which is near impossible.

From ParalyzingBlow?

public override bool OnBeforeSwing(Mobile attacker, Mobile defender)
{
if (defender.Paralyzed)
{
attacker.SendLocalizedMessage(1061923); // The target is already frozen.
return false;
}

return true;
}

From BaseWeapon?

public virtual void OnBeforeSwing(Mobile attacker, IDamageable damageable)
{
Mobile defender = damageable as Mobile;

WeaponAbility a = WeaponAbility.GetCurrentAbility(attacker);

if (a != null && (!a.OnBeforeSwing(attacker, defender) || SkillMasterySpell.CancelWeaponAbility(attacker)))
{
WeaponAbility.ClearCurrentAbility(attacker);
}

SpecialMove move = SpecialMove.GetCurrentMove(attacker);

if (move != null && (!move.OnBeforeSwing(attacker, defender) || SkillMasterySpell.CancelSpecialMove(attacker)))
{
SpecialMove.ClearCurrentMove(attacker);
}
}
