As title suggests my problem is missing tokens, at random intervals tokens will just cease to work on the site in question which makes any webform entries that are emailed out to a client appear empty. It also gets rid of all metatags from pages.
I am unable to see any errors in the database logs, no warnings/notices around the time of this happening either. Haven't got Entity Tokens enabled. The behaviour seems entirely random. I have read en earlier question with similar problems being caused by Node Export, I do not have this installed either.
Latest Drupal Core, latest Metatag, latest Webform versions. Infact everything is latest version as I ran a bunch of updates hoping that would fix the ongoing issue.
The URL Alias Patterns page is also empty, regardless of whether I have run drush rr and appeased the bug.
SimpleTest run on Token results in 0 fails 0 exceptions and a few debug messages that don't seem relevant.
Webform seems to be the culprit here, as it happens more often when I'm submitting webforms, though I'm not sure if it is. Version 4.1 of Webform.
Any help/ideas greatly appreciated
