I read through every entry.. can't remember what order. It was the first time I opened the codex and it sent me back to the part where Killigan was cleaning his room in the prolong. I went downstairs and then there was a plate of flowers.
I found a bug. After I read the codex while I was meeting with Macsen in the tavern the second time (the map was just stolen) I suddenly found myself in the beginning of the game in redroot where Killigan was still a child.
