Uh oh! Does he run a dedicated server? If so, it's a dedicated server issue. Dedicated Servers don't like modified core RTCW files at all, we use those wolfanim.script files to update the player animations for the axis and allies. You could delete them (or choose not to run a dedicated server) but the 3rd person player animations are gonna be pretty awful.
I'll look into it further, i don't run dedicated so i never noticed those kinds of things and when i try to run dedicated RTCW locks up so i never noticed. Sorry about that.
