I die when i switch weapons, how can i fix it?

This happen to me before.

If you have FilteringEnabled on, it will kill you when you unequip. To turn it off, click Workspace in studio and uncheck FilteringEnabled.

If you want FilteringEnabled on, you have to go in the gun's script named, "clientMain", and replace the onUnequipped function with this:(hold CTRL+F when your in the script and type: function onUnequipped, then replace it with the code below)

function onUnequipped(deleteTool)
    if Selected then
        Selected = false

        breakReload = true

        --------------------[ RUNNING PLUGINS ]---------------------------------------

        for _, Plugin in pairs(Plugins.OnUnEquipped) do
            spawn(function()
                Plugin()
            end)
        end
