Putting a caster tome (the one you find in chests) in Akashic Tome, then removing that caster tomefrom the Akashic Tome remove Its name.

Step to reproduce :

• put akashic tome and a spellbook in crafting area
• take the resulting craft
• equip the akashic tome, switch to the spellbook
• press shift + drop item
• the book is now removed from the akashic tome, without its fancy original name, its now named like "Caster Tome of Air"

Only the name? Not the spell as well? The name is just a normal data component like everything else. I would suggest reporting it to them.

Nope the spell is still here, only the name. I also notice that when you switch the akashic tome to a caster tome the akashic tome switch to another one from the one I've selected

I don't know If reporting it here is the right way or I should maybe report it to the akashic tome repo
