Content cooking error

Yup getting the same issue, started a few hours ago. When I rollback to a version that was working this morning and last night it still breaks but when I rollback to before the last update it works so looks like whatever that thing was that ran when we opened our maps after the update and changed almost all our assets is causing the issue and they changed how it was handled server side a few hours ago. This is just my speculation after wrestling with it for a few hours
