As the title says, the hook grapples to the player resulting in it not doing anything in multiplayer. I don't know if this is a conflict with any other mods, but it makes the hook unusable. I would imagine this could be fixed by making it so the wielder can't be hooked onto by their own hook or the hook could spawn slightly offset from the player

I found a fix (at least for me), the problem seems to be this control

when I change it to something else, it works perfectly. It's red because right click is also bound to the Use/Interact control, when I unbind that one it also works normally.
