1. Start a new Game with an Archer (I kept a bow as a weapon)
2. Proceed to the quest 'Find the Den'
3. Enter 'the Den'
4. Observe that the quest fails to be updated after entering 'the Den' which leads to a Progression Blocker.

Note : I restarted completly the game and went back to 'the Den' and that time a ''NEW'' pops up in front of the 'Find the Den' quest as this :
'NEW > Find the Den',
and I was able to enter 'The Den' with the quest getting updated and a cinematic after. It is possible that the issue may have a link to this ''NEW'' pops up that can sometimes fail to pop and prevent the player to continue.

I have a screenshot with me getting in the Den and nothing happening there if needed. (I don't see a way to attached the screen here)
