Can anyone confirm this bug in CSOM for me? Also if the beautiful people at Microsoft are watching, i'd love for this to be resolved :) 

$siteUrl = ""
$Username = ""
$password = ""

 [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client.Runtime") | Out-Null
 [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client.Publishing") | Out-Null

$Password = Read-Host "Password for $Username"
$SecurePassword = $Password | ConvertTo-SecureString -AsPlainText -Force
$SiteCredential = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Username, $SecurePassword)

$context = New-Object  Microsoft.SharePoint.Client.ClientContext($SiteUrl)
$context.Credentials = $SiteCredential
$quickLaunch = $context.Web.Navigation.QuickLaunch;
$context.Load($quickLaunch);
$context.ExecuteQuery();


$node = $quickLaunch.Item(0) # THROWS ERROR HERE
