Scrolls of Deception disappearing

I had 2 scrolls in my bags, and now they are gone. I earned another from bg and 2 hours later its gone. wasn't a big deal at first but now its kind of a problem. I've donated for scrolls, and they are obviously beneficial. Why are they just vanishing from my inventory? Other people have brought this to attention and its still an issue? thanks in advance.

Yep same thing happend to me and my friend.

same here and a bunch of other people, contacted and they said theres nothing they can do about it :p surely they can check the item logs or something but idk
