Quest completion bug

[ImHorROr]

talking with the guard again will make me complete the same objective twice how to stop this?

Yep, that bug has been noticed before. I forgot to put an IRR to the instructor to get that patched.
This one can be nipped in the bud with a small change to QuestStatus.CompleteObjective:

        public void CompleteObjective(string objective)
        {
            if (quest.HasObjective(objective) && !completedObjectives.Contains(objective))
            {
                completedObjectives.Add(objective);
            }
        }

By adding the check to be sure the objective hasn’t been completed already, this should prevent multiple completions.
