I cannot seem to use Spellbook of Fate.
http://i.imgur.com/ferJ7ap.png As you can see in the above image, I have a Spellcaster-type monster on the field. There are 2 Spellbooks in the graveyard. I should be able to use Fate's second effect to flip Spellbook Magician of Prophecy face-down.
This screenshot is taken from the very start of my turn - no other cards or effects were active, Spellbook Magician was already on the field.
I drew into Spellbook of Fate.
At that point, that error message got spammed.
[Script error:] [string "./script/c97997309.lua"]:55: attempt to index global c"38049934" (a nil value)
I cannot activate Spellbook of Fate, only set it. To repeat, there are 2 Spellbooks in the Graveyard; Grand Spellbook Tower and Spellbook Star Hall.
Next turn; the opponent Special Summoned Tarotrei, and destroyed Spellbook Magician of Prophecy.
Next turn; I drew into Black Fang Magician (another Spellcaster). I normal summoned it. Still could not activate Spellbook of Fate - so this isn't an issue about "targeting" introduced by Pendulumgraph (even though Fate does not target).
I tried Setting 1 of those Spellbooks of the Master.
At that point, the same error messages appeared all over again, just like in the screenshot.
