Ahoy! I have one thought about doing maintenance to that quest. Read well.

While talking to Magdelena Vendelino, the cutscene camera should focus on her while she says her line, "Yes, I can read this. It is a simple code the Armada favors. I see the books you are looking for. It seems they have been sent on to Cadiz.".

That's it. Hope it gets done soon. My thanks!
