where do we spend the favor points?
in game? or outside in the menu?
to spend favor points either hit F4, or click the Trophy looking buttom, bottom right next to your item slots.
this is also a known issue that the favor points are messed, from the looks of things though its not on top priority to fix as the multiplayer 'playability' is what they are working on right now. but hopefully they take a look at the favor point system soon, and the random 'failure to respond' unit actions.
