Extract mission dl3-04.fs2 using VP-View (or any other effective VP viewer/manipulator program). Open it in FRED2_Open (make sure you're using the proper -mod command if you're using a mod directory) and select from the ships editor, the SC Zhar (Rackshasa class). Under its arrival cues, there are 2 requirements, bound with an "and" logical opperator. One of the 2 requirements should be a check to see if event "Got too close to ares" is false. Select the "is-event-false-delay" entry and right click on it. Then select "replace operator" from the drop-down menu, then "event/goals", and finally "is-event-incomplete". The original event name should be retained. Save the mission, exit, and replay. Remember, this ship's arrival is key to the arrival of the rest of its friends. It will not arrive until 40 seconds after event "command are you listening?" comes true, so be patient when playing it.
Later!
