WPF disappearing

[Ubermac]

I put a point in Weapon Mastery, then the WPf points into throw. Minute later all WPF is gone. I tried that a second time when levelling again, same thing happened.
Now on the website, i seem to be missing 1 agility and 1 mastery as well, but my level seems to be correct.

Are these known bugs?

Same bug here, except that I lost 1 hundred WPF - I raised my 1H in game, and some time later it was gone but I still had my skills and level updated - scary
