I'm having the same issue - 3rd character running through campaign (hunter) and not able to finish due to the last portal issue you mentioned above. Glad it's not just me. Frustrated that it's happening though! I just want to be done with this campaign already. I wish Bungie was more supportive of Alts so you wouldn't have to run through the same content on 3 different characters... give us a skip option please! Also, please hurry and fix this so I can start the pinnacle grind (another system that needs a lot of reworks!)
