My daughter's playing the game and when she picks up either the letter or the book, they disappear completely from her inventory. She couldn't read the letter, but we managed to find where the book was by watching a YouTube tutorial, however now that she's got the book, we can't advance it anymore since she can't find it in her inventory, even though she definitely picked it up.

Any ideas why these would be disappearing? I tried moving the mod to the end of the LO but as it's a master file, it didn't like that idea.

(I should mention this is on the Xbox series X - I didn't know where else to contact you)
