Tome of Kurak disappearing on thumagatory bench

Sorcery has been out since September 1st and ever since I took a yellow lotus potion I have not been able to upgrade my book any further, it doesn’t even show up on the table. Please look into this, I would really like to enjoy sorcery.

Use a Potion of Natural Learning from the Midnight Alchemist trait, yellow lotus potion’s been broken since time Immemorium :adnyshake:
