Well, i completed the first few missions of TTK. After finishing the mission where you destroy the dreadnaught superweapon, i went to the tower to get the next part of the quest line. I talked to cayde and zavala, and zavala handed over the "Enemy of my Enemy" part of the quest. For some reason, it skipped making the Dreadnaught an available area. That means my titan can no longer access the dreadnaught, meaning my titan cant really do anything. Ive tried going back to the tower, talking to them, etc, but nothing has worked so far. Help would be wonderful.

Patrol beacon mission comes near fhe end. You have to follow the quest line and complete Regicide, then you'll get the missions to plant the beacons and open up patrol, along with your sword quest.
