So, I'm unsure whether it's a *bug* per se so much as a menu design or usability issue, but:
My first two characters designed with HL are a sorcerer and an inquisitor, both *human*. There's a human favored-class bonus which allows, for these classes (as well as other spontaneous-cast classes) an added spell-known per level, spell to be one level lower that the max level castable.
In neither class - sorcerer or inquisitor - does the bonus spell menu seem to work.
Initially, at any level it will only offer zero-level spells. Now, reading the (somewhat unclear) instructions, one must add the feature each-for-each, then go to in-play to tweak the level, then come back and add it (or something; it's confusing). The fact is, it simply doesn't work, and strikes me as a coding issue (I say this because the feature seems to be a modular issue affecting all spontaneously-casting classes which have the favored-class bonus available).
What *should* happen is that the menu should refer to the class level of bonus selection and offer spell levels accordningly; so - to use a sorcerer as an example - at levels 1, 2 and 3 the favored-class bonus menu should offer +1 hit point, +1 skill point and bonus spell: 0; at level 4, it should offer +1 hit point, skill point, bonus spell: 0 and bonus spell:1; at 10th the bonus hit point, skill point, and bonus spells 0,1,2,3 and 4 (all separate entries, and so on.
(I know it's a known issue, but it seems persistently unresolved - and not too difficult TOO solve - so I mention it again

)
