Dear Forum, I've been playing through most of the questlines, however I never seemed to be able to finish the Limbo Theorem. After searching through my entire inventory and foundry list I can say that I do not have the Limbo Neuroptics. Perhaps I've had them but sold them, however I am not able to complete this mission, is there a way for me to reset this quest and redo it? Yours sincerely, Ahru
