Add Side Meta Box Reset Post Data

[wilhud]

When I setup a meta box located on the side and then run a WP_Query to pull some data for the post Meta Box, I encounter a problem when updating the post. Even though I have called wp_reset_postdata after my WP_Query, it still seems to hold onto that new query when I update the post. The slug suddenly changes to the name of the post in the meta box. However, when I move the meta box to the normal position, the issue does not occur.
