SetForcedAnimation Starts at a Random Animation Frame

Why does SetForcedAnimation (using it serverside) start the animation at a seemingly random frame every time? Sometimes it look very nice, sometimes, it seems like it starts at the very end of the animation… how do I force it to start at the animation’s first frame?

edit: oh I thought it was a default gmod function oops its part of clockwork…
Well I’m trying to fix the issue where the stunstick raising/lowering animation doesn’t always play properly
