Mission 8, Ghouls and defiled heroes do not attack or rarely attack.

For some reason, in mission 8, Ghouls don't want to attack really, more prefer to wander rather then attack, the "mark for death" ability doesn't seem to work at all, and none of the spirit heros I summon by defiling are actually attacking unless I posess them, I tried this by sending them on their own to a spot, but they just wandered around the flag doing nothing.
