Problem: I cast monster summoning 2, so that it summoned hobgoblin archers. Once they are summoned they move around of their own accord, ignoring orders. They move to seemingly random points periodically. Disabling party AI had no effect on their movement.
Expected Behaviour: All summoned creatures to be directly under the control of the caster and to follow his orders expressly (without acting of their own accord) unless the spell description stipulates otherwise.
