Queen Sigma achievement locked?

[GiRaf]

Hi,

So I unlocked the Forbidden Scrolls of Morbane today and decided to test some spells out. I randomly entered a few spells, one of them was to unlock Queen Sigma (hadn't unlocked her yet). Then I finished the game by beating the Directer (yes, after speaking to him 2 times previously) in Eudaimonia Machine (3 times, with 3 different characters). I got the end credits and the fireworks, so I thought this would unlock the Greatest Jubilee but it didn't. It's the last item in the collection but I don't know how to unlock it now...
Any ideas to solve this issue? I'm afraid that using the spell to unlock Queen Sigma (which is usually unlocked through completing the collection) blocked it.

Thanks <3

The "Greatest Jubilee" is unlocked by clearing the final boss, but that does not add it to the collection.

To add any item to the collection you have to find it naturally in a run (from a level-up or a chest). Using Big Trouser and taking the "Jubilee" as your first item will not unlock the item in your collection.

ooooh thank you so much, that makes more sense. I'll keep trying then :)
