Error?

I just received an error IN GAME.
An interesting message popped up.

    Error
    dobj for xmodel
    'c_rus_spetznaz_body1_g_larmoff' has more
    than 160 bones (see console for details)

WTF is going on?
It made me quit the game and lose my level progress.
I've seen glitches, but never a message pop up.
