Spotted three bugs:
1) The recipe for the Scroll of Jump located in the second barrel on the platforms just before the exit to the caves under Caer Lum is bugged. It reads "Jump" 2xAbyss Moss and 1xAngry Violet. However, when read, the same recipe reads "Mage Armor" on the party crafting screen. The picture is a jump scroll, and crafting it makes a jump scroll, so this is just a typo.
2) The Silent Whisper Parchment found in the caves under Lum is missing the last faction icon.
3) The game allows players to copy spells they already know into their spellbook again. I copied Color Spray to my mage's spellbook, even though my mage already knows color spray. This destroyed the scroll and charged me 55 gp, but it did not use a page in my spellbook.
