currently the hidden advancements for spirit/familiar rituals are not completing/registering at the time the ritual is performed. I've tested with all the familiars, and a few spirits, and the only one that registered was the drikwing. The advancements are there as i can grant them to myself through the /advancement command.

tested on enigmatica 6 version 0.5.14 which has occultism 1.14.1

Did not test with just occultism installed as i dont know how to tell if i got the advancement or not without my quests. My quests do complete if i trigger the advancements manually through commands
