Miscellaneous: Spells Scrolls Returning After Using them

[Burrito]

While in Neriak, I purchased by Level 29 Spells for an enchanter. I memmed the spells into my spellbook and zoned. After entering another part of the city, and crashing on the zone, I realized that I had 3 of my spells in my inventory. Thinking it was a graphical glitch, I tried to remem them. The spells were still memmed, and I was basically refunded some of my previous spells.
