For the "Rob the Protectorate Warehouse" quest I decided to go full hostile, killing the guard in the underground entrance, then all the guards in the warehouse itself. For good measure I killed the workers for no witnesses, although I made a save prior to killing the workers. When I go outside, back through the underground entrance, the Protectorate outside aggro on me. Did I do something wrong, or am I required to go the stealth route. I have no persuasion by the by.
