So a few months ago when I was playing I started an oroboros mission, and it told me the contact couldn't be found for it. ( positron task force I believe it is ).

Well it won't let me abandon the mission, I've tried talking to positron in steel canyon and he wont' help me, and i can't abandon the mission in oroboros either.

How do I get out of this mission so I can finish trying to get to level 50 before the servers go down? x.x
