Did this patch do something to the Necromancy of Thay and Dark Amethyst. I've long since found both and opened the book with my main character. I kept the Necromancy of Thay in a separate pouch within my inventory, which I used to carry other quest items to keep things less cluttered, and the book is now back in my inventory and I can't put it back into the pouch. The Dark Amethyst has also appeared in my traveler's chest even though it should be in the book. I didn't know what it was at first since I used it so long ago. I thought maybe it was something I looted and sent to camp by accident since it has the quest colored border, but I couldn't right click it to examine it because there is no right click menu for it.
I don't know if I did something in-game and it was a coincidence that I noticed it after this patch. This may also be related, when I changed locations and went to camp, a bunch of junk (like bones and bed rolls) from the previous location got sucked into the traveler's chest and moved with it.
