Weird two-handed fighting bug in Gothic 2: NOTR

Alright, I'm a level 31 Paladin, wielding the Claw of Beliar, and fighting the fire dragon. I'm at 60%, or Master level, with two-handed weapons, but all of a sudden my character wields all two-handed weapons as if he has no skill at all. As I'm sure you can imagine, this is annoying as hell. Any way to fix this?

Not funny at all, but I think it's best to cheat when this happens. When you have the console, type 'edit abbilities' (it fills it in automaticly after typing the first few letters). In the next console screen you can type 'LP = xx' with xx the desired number for learining your skill level again.
