Icebound Passage blocked Fangs of Asterkarn

I’m playing Fangs of Asterkarn for the first time and I’m on the “Journey to Kurnhold” quest. I spoke to Ulfgarn and he gave me the Mark of Passage, but when I approach to the place where the quest says I should be able to enter the Icebound Passage it’s blocked by a wall of rock and ice. I no longer have the Mark of Passage in my inventory, and cannot proceed.

My quest objective currently says only “Traverse the Icebound Passage”. Returning to Ulfgarn and speaking to him does nothing to progress the state of the game. Restarting the game session also doesn’t help. It seems like I can throw my Grenado through the rock wall, so maybe it’s in some weird partially active state, but I can’t walk through it.

Any help is appreciated, as I haven’t found anyone else who encountered and reported this.

Restart the game to get the latest hotfix.

Thank you! Having Steam verify the integrity of my games files seemed to resolve this as well as a few other state issues with quests I’d encountered.
