Feature ID not assigned when saving a list as a template
After saving a list as a template, the file created in the template gallery does not have a feature ID or product version associated with it. Also, when creating a new list dialog, the list template is not available as an option.
This can be caused by having the 'ParserEnabled' property on the SPWeb set to 'false'.
Use PowerShell to enable the 'ParserEnabled' property for the web site:
$web = Get-SPWeb <url of web> $web.ParserEnabled = $true $web.Update()
