So i started playing Destiny 2 about 3 months ago, i played the game got the rats king quest by completing the enemy of my enemy quest line. I took a break for a bout a month, i come back and grind some more. now keep i mind when i started it was not season of opulence. Now it is and my rats king quest is gone my enemy of my enemy quest line is gone not showing up on titan, and my door says locked to get the fallen transponder. Oh and get this i look in my truimphs for the quest line it says not completed. Bungie please help there are no fixes on youtube,reddit, etc... Thank you, AstroLogic
