Bug at Solas' memories.

Hello, I have an issue with the mission related to Solas' memories. I'm missing one last statuette, but I can't obtain it because there's some kind of invisible barrier blocking my progress.

I've tried reloading my save, but it doesn't work. I've also tried closing and reopening the game, but the problem persists.

I know this mission is important for the game's ending, and I wouldn't want a bug to affect my experience.

Any solution? A future patch to fix this, perhaps?
