Islands breaks client side routing

[tyler-harpool]

Islands seems to break client side routing. Here is my dep and home.rs.
I get hydration warnings, runtime error unreachable, called Option::unwrap() on a None value which I do not know where to look next.

home.rs, using the example from the book.

    view! {
        <h1>"Welcome to Leptos!"</h1>

}

#[island]
fn Counter() -> impl IntoView {
    // Creates a reactive value to update the button
    let (count, set_count) = create_signal(0);
    let on_click = move |_| set_count.update(|count| *count += 1);

    view! {
        <button on:click=on_click>"Click Me: " {count}</button>
