[2021] Converted sister lich does not show up in Codex !

I see that on Saturday you converted a sister ("Appinia Mutillironek"), and I see her in Codex>Universe>Sisters of Parvos. If you were unaware, her status will be listed as Untradeable Converted and she will not show up in the Crimson Branch because you can only trade a lich or sister once.

Does that explain the mystery, or is more investigation needed?
