 * I can’t really figure out why, but there is a problem in the function:
    `get_preview_postmeta`
   line 127
 * I do use a custom theme with the function `get_post_meta()` in my single.php 
   to retrieve the saved values. When I look at the page in preview mode, i _sometimes_
   can’t see any post_meta data, sometimes i see outdated post_meta data, sometimes
   only the post thumbnail is missing (stored in post_meta with key _thumbnail_id).
 * Everything is alright if:
    - i publish the post
    - i deactivate the function get_preview_postmeta from your plugin
    - it even works if i use the preview-button in upper right corner, where the
      url has all these parameters: ?p=3398&preview_id=3443&preview_nonce=fb39e854cd&
      _thumbnail_id=3404&preview=true – all other preview buttons don’t have theses
      parameters and will fail
 * Does this help you to understand the bug?
