Weapon animation bugs

I've not played the game with the new version (0.9.5 + Patch 1), so yesterday got back into it again and played with some guys at the [TKG] The Killing Crew server, and I've spotted some weird bugs happening with the animations of the Knife and the Dual Colts - the animations are not always showing.

Maybe something was mistaken in the code and this problem can be fixed because before they were working right.
