Every server I have loaded, I cannot shoot, aim, or melee. I can interact with the environment and still use all other controls such as lean, move, sprint, crouch and others, However, no matter which key I bind it to, I cannot attack in any manner. Sometimes when sprinting and spamming the attack button it'll allow a single heavy strike melee, but it will not do it when aiming at anything and only does it when sprinting forward.
