Not getting the Black Morrigan Link Recipe

I purchased both the Black Morrigan and a Craicic Sand Spitter from players. On placing the Black morrigan into my bestiary, I received the recipe to modify the number of sockets, but I did not get the recipe to modify the number of links. I have never captured either of these beasts myself. If this is part of the mechanic and I need to capture one or both myself, I'm happy to drop this report.

Things I tried: Leaving and returning to the menagerie. Restarting the game. Itemizing and re-releasing the Black Morrigan.

I also have this bug!

Same here, only the 6-socket recipe unlocked.

i thought also it was a bug on my account . but i got it fix . you need to hunt yourself the criac sand spitter and black morrigan in maps. for the 6link to appear.

I got the same bug, so I hunted it myself, still can't get the recipe.

Same issue, missing "Apply a Hinekora's Lock on a Magic item" despite having multiple Black Mórrígans and Craicic Chimerals

Same issue, i'm missing Aspect of the Spider lv30

Had same trouble.
When i captured Craicic Sand Spitter itself i got recipe "to Have Maximum Possible Links"

"Same" issue here
I am missing the 3 way split recipe...

got the same bug didnt get all the recipes and despite having the beasts i cant even use the crafts that I unlocked
