Beneath The Meridian, Tunnel Bug

Hello, my epic name is bananagoat1 and I’m having a issue on true vault hunter mode mayhem 3 on the mission Beneath the meridian. Everything was going well got to the end of the neon arterial map and now there is no way point to go to the next map. And the mission objective of find the tunnel is complete but nothing is updating after that.

Have the same problem. After researching and doing side quests, fast traveling to other areas, restarting game with no luck. Started a new character hoping it gets patched.

How there is no answer to this? Even a year later, nothing? If you run fast through the map, its getting stucked. Happend twice to me already. This shouldnt be a very complicated thing to patch.
