When post is updated, custom metadata in text area field is overwritten

I Found my mistake. Basically, I had a bad prefix… I changed the function name of the get_post_meta to $gwrrest_stored_meta but then missed it in the echo of the text area content. I had “recycled” my code and accidentally left is as $prfx_stored_meta.

So the line here: 

 <textarea name="specials-textarea" id="specials-textarea"><?php if ( isset ( $prfx_stored_meta['specials-textarea'] ) ) echo $prfx_stored_meta['specials-textarea'][0]; ?></textarea>

Needed to be changed to: 

<textarea name="specials-textarea" id="specials-textarea"><?php if ( isset ( $gwrrest_stored_meta['specials-textarea'] ) ) echo $gwrrest_stored_meta['specials-textarea'][0]; ?></textarea>

Hope that helps someone else.
