I have saved, killd a group om mobs, when back to the save and increase the crossbow skill and killd same group om mobs. I did this several times both with first and second skill level and come to the conclution that the crossbow skill do not give the extra damage as the skill description says.

Same thing for axe skill. Im about to test the rest of the weapon skills but initial test show that all skills that give a fixed range of extra damage not work properly. The skills that give a % increase seems to work.
