Game Mechanics: Memming to a 9th spell slot

[captnamazing]

I was recently soloing Lguk on my enchanter. After killing some merbs, I had to swap around spells.

Now, as a clever player, I click the icon in spell book and then press Alt + # to mem it to the spell gem relative to the '#.' In his case, I usually mem gate to #8.

However, I pressed #9. Gate memmed. I could not remem it. Nor could I unmem it. I had memorized gate to a non-existent 9th spell gem.

I could even START casting, but it would autointerrupt after about half a second of cast time.

The only way to fix the problem was to throw myself into a horde of froglok ghouls and get gangbanged until the sins of my forefathers were erased as penance.
