I recently created a titan and used the spark of light that came with the TTK. After I went to the Tower the first few times and started the second part of the vanilla story where you have to complete the first 2 missions after Restoration. Ever since then I can't go to the tower with just this character. I have to go to the Reef to get bounties and turn in Engrams but I locked out of everything else that is exclusive to the Tower. I have tried to change my light level, even restarted the game. Its been like this for over a day now. Is there a fix for this?
