I add a couple of taxonomies to a meta box. Up to version 4.3.1 these worked/saved fine.
Updating to 4.3.2 breaks this. Any save of the page changes these to the default category. This happens whether I change the choice or not.
Here is a screenshot of what happens after a save: http://cl.ly/image/3H3s3H2K1w0F
Reverting to 4.3.1 corrects the issue.
