I can't really say anything about retcons but for contradictions, I can name an examples.

One is related to monsterization regarding elementals as a human woman is incapable of becoming one however a line in the fallen maidens book and detailing examples of how someone can be monsterized implies that a human women could become a yuki onna.

Thats one example I've found.
