Playing a fanatic purifier, and apparently this situation only activates when you survey the grave mound. As Tiyanki were considered hostile, my science ship couldn't do that until after they were all eliminated, and now there's no way of closing it.

Does anyone know the console id for this event, or however you force it to finish? The debugtooltip does not give me an id, and the id numbers in the wiki only say "cannot find event" when put in.
