Forum:Vanishing Book Glitch

SO yeah I found a glitch that keeps happening with my Sims. I got The Sims 3 Pets for Xbox and I'm trying to move to a new house. My sim is an author and I really wanna keep her books and bring them to the new house. The books are in the off site storage currently however when I try to take them out of the offsite storage they vanish from my normal storage. This has happened before and I was forced to delete every book I had made. I don't want to do that again.

Can anybody help me get rid of the glitch or save my books? I would just restart the game and go back but i had saved it with the books already int he offsite storage. Please help.

(Btw I'm totally new to this websites Thread/Discussions format. So if i do something wrong please forgive me)
