I recently bought the DLC for this game and tried the shadowkeep quests. I got to step 3 of 19 and I cannot progress. Eris has nothing for me (despite her icon flashing as if she does) and there are no missions or anything visible anywhere on the moon. The specific step is "Complete the quest "Essence of Despair.": "Essence of Despair" completed"
I've done some research and other people seem to have had an issue at least similar to mine, solutions there say to pick up the quest from the postmaster. This does not work for me. Other people have also said you need to do activities on the moon, this also did nothing for me.
This is quite frustrating having spent a not-insignificant amount of money on the game. Please help
