Roden Healer Lifepath

In the Codex, the Healer and Mayor lifepaths on page 438 and the Preacher lifepath on page 443 all list Philosopher under the Restrictions section of the lifepaths. Since this lifepath isn’t anywhere in the Roden lifepaths, should I just assume it’s a mistake?

I believe you are correct. If I recall rightly, Topi cut the Philosopher lifepath at the last minute.
