Thanks for the bug spots. Expect fixes in tomorrow's update.
Losing patrol notes to the monster hunters *is* intentional but its not really indicated properly in the UI. I'm going to be creating a 2nd story loot type for them soon.
The patrol notes will be rebalanced in tomorrow's update as well, it was a bit wonky and I just hadn't fixed it yet.
You can see inidividual spells bonuses in the inventory screen (click on spell book) but I need to add UI for overall bonuses. Promise they are coming soon!
