I also found that Galeoth's Third Box does not appear in Chapter 6 (aka after you rescue him).
In Chapter 5, this is a long-standing bug, but when you kill the Satyrs and that Mage guy asks you to buy an item from him; he offers 4 items and 2 of them you can purchase just fine (mega ring and adept staff), but the other 2 (power orb and energy orb) are forever listed as 0 charges and you cannot purchase them.
Edit: also the spellbook spells Volcano and Inner Fire; I chose the upgraded versions that say "removes the global cooldown" but the global 10 second cooldown clearly still activates when I use them.
