Windows server 2012 running build 93.
Models.json.gz should be 52K but now its only 32K, stuff has just evaporated.
Second time this week, but this time a completely different load of content GONE completely from the models.json.gz.
And the backups are working which means its been overwriting the good backups with the broken models file.
I have done no deletes, there has been no changes and there is nobody who can delete stuff. The stack manager is doing it all by itself.
