Here lies the Abyss Marker Disappeared

Hey,

I am playing the game on PC. After I talked with Hawke and Loghain, the mission marker appeared near the Bridge. On my way there, I figured I'd talk to the Naturalist as well and get that quest advance. I talked the Judith and updated the quest, also got the Wyvern quest. But now the Marker has disappeared. In Journal, it says Meet Hawke and Loghain at Western Approach. So the quest progression is still there, but I can't unlock the mission for War Table. Any advice would be appreciates
