Hi, I have a rack currently on 20190111211123. After upgrading the rack to 20190126182547 (which is the version offered by `convox rack update` without any other params) I am no longer able to deploy an app. The error I see in CF is this: 19-03-25T05:28:33Z system/aws/cfm integration-digivizer-app-ResourceDatabase-KP903E37IO6Z UPDATE\_FAILED Instance CloudFormation cannot update a stack when a custom-named resource requires replacing. Rename integration-digivizer-app-resourcedatabase-kp903e37io6z and update the stack again. 2019-03-25T05:28:34Z system/aws/cfm integration-digivizer-app-ResourceDatabase-KP903E37IO6Z UPDATE\_ROLLBACK\_IN\_PROGRESS integration-digivizer-app-ResourceDatabase-KP903E37IO6Z The following resource(s) failed to update: [Instance]. Does another step need to take place before deploying the app? ---

We’re seeing this too on a database of ours. Did you find a resolution to this? EDIT: Turns out we had accidentally changed the `encrypted` option of the database, which Cloudfront interpreted as needing to replace the database.
