I've had the AC scroll bug problem, and stumbled upon a fix by accident. Here's the fix for the AC scroll bug. As soon as mailce/torment wears off. Click on your scroll again. You will get the animation as if you have rescrolled plus your scroll and bonuses shows back with the same time as when you got malices/tormented, but your scroll count stays the same. So if you have 15 ac scrolls, get maliced. Malice wares off, you click the scroll again, get scroll, scroll time, and bonuses back. And you still have 15 ac scrolls.
