Observed behaviour

When using a spellbook with X spell slots, using the Quick Cast shortcut for slots above X throws a java.lang.ArrayIndexOutOfBoundsException and crashes.

Expected behaviour

The game should ignore the shortcut if it is invalid, or at least display an error, not to crash entirely.

Steps to reproduce

1. Get any spellbook. For instance, the Ironbound spellbook. It has 5 slots.
2. Use any Quick Cast shortcut above the available slots. With the Ironbound spellbook: any slot above 5
3. The game crashes.

No response

yep. this is a pretty dumb oversight on our end. im surprised no one has run into it sooner

I assume nobody ran into it because keys being valuable in large modpacks, they used the spell wheel instead.

Thank you for the fix ! Keep up the good work, your mod is incredible !
