Farrul, first of the plains Beast

Bought Farrul, first of the plains beastcraft of market, added him to my
beastiary, but cant seem to do the aspect of the cat recipe?

Do I HAVE to defeat the boss inside the den first? (didnt need to last league)

i have the same issue with Fenumus, First of the night. My blood altar literally "forgot" the recipe, it's not even listed as unusuable.

I think it has something to do with a bug they informed us about last report

"Bestiary's Blood Altar no longer filters the level of beasts for the first slot. A fix for this is being worked on. For now, manually select an appropriate level beast in the first slot, if available."

Since the recipe is missing, (its not labeled unusuable, its straightup entirely gone) there is no way to select anything manually unfortunately. But y, maybe its related somehow.

Its gone for me too!

Same thing happened to me. Hoping for some good news. Or else good bye to 20c
