Views were not accessible after shutting down a server

Hello,

We accidentally shutdown one of our servers manually. We added a new server back and re-balanced as soon as we could. Everything seemed okay for 30 minutes then we started getting the following errors

Noticed exception 'CouchbaseException' with message 'case_clause: {not_found,deleted}'
Noticed exception 'CouchbaseException' with message 'error: revision_sync_failed' 

We had two design documents and we were not able to access views under one of the design documents.

We fixed it by deleting the design document and re-publishing it.

My guess is that we caused the issue by shutting down the server from our end without doing failure over.

Is this expected behavior?
