I might sound like a dumbass but did you try redownloading the mod or restarting the game?

what worked for me was going to the weapon part of the "Q" menu and typing outlast, a square with the name "*Outlast* Hands Swep" appears and you click it and you get the hands. (english is not my first language)

pov:there is someone saying in roblox booth plaza 2 "♥♥♥♥ is tastey" me:"ALRIGHTY *MURDERS THE 5 YEAR OLD*

hellp

try using VMAnip, as how Dankot said first equip the "outlast hands swep" and it should work
