[Spoilers if you have not finished the game at least once on the 'neutral' path at the end.] We found another odd difference between the two language versions.
When you finally manage to rescue Triss, she starts revealing some facts about the Lodge. In the English version, she mentions there are
nine sorceresses who are members of the Lodge. In the Polish version, she clearly states there are
twelve members. So what happened to the three extra sorceresses during the work on the English translation?
Consulting the wiki, it confirms that the Lodge has (had) 12 members. I think the problem is that at this point of the game, not all of them are alive. Sabrina Glevissig has been burned at the stake, Assire var Anahid was killed by Shilard, and Yennefer is, as we know, missing or considered dead - or at the very least, not a member of the Lodge any more, as Síle confirms that she's alive but seemingly working for Nilfgaard. This would make the current head count (when you meet Triss), 9 members. I'll have to go back and look at the conversation again, but the way it was written gave me the impression that Triss was speaking of the Lodge in a past tense, meaning she would have logically counted all members, but since the numbers do add up if we count them like this... maybe it's the Polish version that's at fault?
