The wiki says Spell Inventory is supposed to unlock after stage 51, but it's not unlocking for me, please look into this. I tried prestiging after reaching this to see if that would work, but it didn't.

At the bottom, it says I'm at 55-1 and 55/75. I'm pretty sure that I'm at stage 55, right? And the 55/75 I think means I get next spell at level 75? Anyway, it would be great to have the option to change spell loadout without prestiging.

Edit: Anima scaling multiplier with number of times you've slept is not working either. I'm pretty sure there are other broken variables that I haven't noticed yet, too.
