Journal entry

As you are, no doubt, already well aware, Geralt has always paid particular interest to crowns and the men who wear them. Kings, you see, are always in need of specialists to perform dirty jobs for them. When Geralt heard King Radovid wanted to see him, he surmised this was just such a moment and set off in the hope a profitable witcher contract was in the offing.
And this time Geralt was not mistaken. Radovid asked him to track down and bring back Philippa Eilhart, a sorceress Radovid hated with a particular fury.

Thank you. I did see this, but I'm asking if it's in the game itself?

Despite doing the commands, there's no journal entry in my log.
