PoweShell Create Item in list but last item does not start workflow.

I have created a PowerShell Script that looks at a data file, converts it to a CSV file, imports it into SharePoint list. 

For the past 5 days,  timer job runs the script and creates the list items and the work flow kicks off and completes on every item except the last one. 

I cannot reproduce on a test system. 

Here is the script.

Script

#Load SharePoint SnapIn
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

#Set the variables here, Do not modify code below this block

    $LogfileName = "C:\Users\Administrator\Desktop\log.txt"

    $TargeLocation = "http://picaso.contoso.com/" #SharePoint URL
    $TargetList = "Carmike" #SharePoint List
    $ArchiveLocation = "C:\Users\Administrator\Desktop\import\archive"

#Set the variables end here

#Update log file that import process started
Add-Content   $LogfileName "*********************************" ;
$a=Get-Date
$msg = "Import started at " + $a.ToShortDateString() +" " + $a.ToShortTimeString()
Add-Content $LogfileName $msg

#Read all the files
$fileEntries = [IO.Directory]::GetFiles($SourceLocation);

#If there is atleast one file to be processed
