(Spoiler alert) Help needed to gather last codex pages.
The codex pages are not showing up in my map.
In my inventory, it is listed that I have 5 encrypted codex pages and 0 decrypted ones.
Leonardo whom's supposed to be in the Auditore's castle is nowhere to be found. The Codex wall's area isn't available and there's no codex page icon showing up in any city on the map (I visited all viewpoints; I have them all cleared 74/74). And still I have the screen title: Codex pages found: 25/30.
What am I supposed to do ? I have to get all these pages to unlock the Codex's wall area.
Please help.
Do you have the Battle of Forli or Bonfires of Vanities DLC packs? If so, you may need to complete those before Leonardo shows up at the villa and the codex map is available.
Otherwise, I am not sure.
Nope, I don't have any DLC pack.
The cd that I have is the first release of Assassin's Creed.
More details on where I am in the game:
After Ezio becomes officially an assassin, Mario invites Leonardo to the Auditore's castle where he'd settle in the same room in which Ezio's sister and the Architect are. I gave him a page that he decrypted then he disappeared and I can't see him nor any codex page icon on the map.
The only mission (memory icon) available is the one in Mario's office where the codex wall is and I can't get there.
Every time I approach the room an audio engages where the Animus' team tell me that I have to possess all the codex pages and that I have a map that shows me the locations of all the codex pages.
The problem is, I spent three days cruising the cities and there's no sign of any left codex pages.
Now I'm starting to think that it's a glitch in the game.
Can I go back to previous missions and start all over from there?
Let's say the one where I have to kill the 9 lieutenants in Florence?

That means you have Bonfire of the Vanities. If you didn't have any DLC, you wouldn't know how Leo got into the Villa Auditore, because they never mention it. Also, the 9 lieutenants in Florence are the targets from BotV.
Don't know about the Codex glitch, though. Never heard of it before now. 
Have you checked Leonardo's workshops in Firenze and Venezia?
YES!!! I have internet back at home.
Everything would be easier with screen caps!!
So...
Have you checked Leonardo's workshops in Firenze and Venezia?
Yep, I checked his workshop in Florence, Venice and even the mountains (thought he might be lost, lol).
Absolutely, no sign of Leonardo.

Now, I'm really confused.
I'm pretty sure these missions are on the main game :/
I mean, the lieutenants were working under what's-his-name, the creepy monk missing a finger that declared a war on knowledge.
Listen guys, I know that it must have been over a year since you played this game and I really appreciate your help.
So here are screen caps, so you can better understand:
This is the door to the codex wall:
That tells me that bla bla bla, I need the codex pages to get in there.
Here's where Leonardo was last seen:
The same room with Ezio's sister and the architect that renovates the Villa.
Here's the weird thing:
In my inventory it says that I have 5 decrypted codex pages. 25 + 5 = 30.
As of the map of all cities, I can assure you, no codex page icon available at all.
So... what up ?
I don't have a clue. I think it's a bug or something. Try contacting Ubi.

Done!
I also attached a link to this thread.
I hope they'll answer soon.
Until then, is there any way that I load a previous sequence and start over from there?
Nope cannot reload. So, you must have the PC version, which comes with both DLCs.
Not sure what could be going wrong...
I found about three people talking about the same problem that I have.
But I doubt they had any solution :/.
I don't understand if it is because of my computer or because of my luck :/
Anyway, I started from the beginning, and I couldn't continue.
Especially because I can't skip the videos. I'll have to wait few more weeks.
Thanks everybody for the help.
