Bug in the Eternity Port main questline where you must assist Morningstar and Lilith in killing a Failsafe's Luminous Avatar. The dialogue asking you to help them happens, and you are given the quest, but the quest does not end when the Luminous Avatar is destroyed. Neither Lilith or Morningstar say anything and the quest remains active. Upon leaving the system and returning, the "Help us [player name]" dialogue plays again, even though the Avatar is already dead, and the two leave the system. The dialogue will then play again whenever you move to a different system.

The following error message appears on the screen:
OnGlobalSystemStarted[900041] Invalid object [Nil] ###(msnAccept missionObj)###
