 > Can anyone else reproduce this issue? It's potentially a major bug, but
 I'm unable to reproduce it with cdwharton's isolated code. I'm tempted to
 say there must be another factor involved such as another plugin, but that
 doesn't necessarily negate the issue.

 Hi John,

 You can replicate the issue with the steps below.

 I've cloned Twenty Twelve theme and literally just updated style.css to
 show different title and added a simple custom meta function to the bottom
 of functions.php

 https://www.dropbox.com/s/2ogfzg54h8rojh7/twentytwelve-bug.zip

 If you get a version of WP 3.5.2 up and running, install theme - go to a
 page, fill out the custom meta. Then upgrade to WP 3.6 - edit that page
 and the custom meta is gone.

 Here is a video of the way to reproduce...

 Incidentally, I've tried it with a plugin and the issue does not replicate
 - I don't know whether plugin meta is saved to a different table than
 theme meta?

 Anyway, I hope this helps and sorry its taken a while to get round an
 replicate.
