Missing quest item (Divinity: Original Sin)

Hello!
I messed up a lot ...
In the Forest of Lukkula, when you go through the main quest and in search of a white witch you come to the lake, you need to fight with the innocent, take a scroll with a spell from them and go to the lake. The scroll is called "Cultist Spell," or something like that. This is the quest item. I took it. But, since I had already played the game once, I vaguely remembered that the lake would send me to Hiberheim, but I didn't want to go there yet. Therefore, I went to study the forest further and do side quests. After 7 (!!!) hours of real time, I climbed the whole forest and decided to move further along the main. I came to the lake, but there was no scroll. I rummaged through all the inventory, began to remember which merchants I go to. I ran around all of them. No one had it. Perhaps I stupidly crafted it, no matter how ridiculous it may sound, because in the inventory it was just in the ingredients tab. I don't look at the ingredients when I craft. Perhaps he just disappeared from me when I reset my characters from the demon at the End of Times (if this is possible at all, a quest item after all).
Can someone tell me how to get the damn quest item back? Save Editor does not work with Enchanced Edition. The save was left alone, when I still have this scroll, everything else was rewritten several times, in 7 hours of play. Replay from that moment is VERY reluctant ...
