Not sure if The Lodge is the place for bug reports but here goes.

Ran into a strange bug with a Replicator field. One of the fields in my Replicator set was a simple type:text field but if the content was (exactly) 'Yes' it changed to '1' at Publish, if the content was 'No' it was left blank, if the content was anything else it survived intact. Changed affected field to type:textarea and the problem disappears!
