i've gotten everything in havana except for one manuscript (and all the pages i don't feel like chasing flying pages again right now). it's in the north eastern cornerish in a fort. i can literally be a few meters away from it on the other side of a barred window. i've found a way into the interiour of the fort and got all the other items but i can't get to that one corner where the manuscript is. i swear i've covered every inch of the fort is there a problem with the game or something?
i tried to find it for so long. it's obviously in the outer ring of the fort but there is no way to get to that corner of the outer interior. in the courtyard there are 4 exits. two lead into the interior where i found a chest and one leads to the exit to outside. the other one is closed and can't go in there. and that is where the corner with the manuscript is.
