Started yesterday, continued this morning. I have (1) character that’s completed the main storyline, now running the Quest Echoes. After completing 2 of them, I switched to another character, ran some non-Quest Echoes without a hitch. Now going back to my main character, the next Quest Echo (Altar of Flesh) just hangs until I kill the game.
As a test, I tried going to other parts of the game, this works as expected. Now the next Quest Echo is locked and my progress has been halted.
