This is a fix to avoid the flamethrower hose to stretch to Pyro's left hand. Since the bone is unused and the only function is to mess with the model, I changed it to a jigglebone just like the original mod made by Sierra Foxtrot.

This fix works for all flamethrowers that uses the base model (like festive, backburner and bot killers)

File have been updated to include a small guide to Valve on how to fix it in case the originally provided files have no use.
