I found a manual fix for anyone that is having the same problem and their plugins are handled through something external to wordpress.
I basically activated the new version. Deleted everything that had appeared in the new version field groups. Run
UPDATE wp_options SET option_value = ‘4.4.5’ WHERE option_name = ‘acf_version’
on the database.
Replace ‘4.4.5’ with whatever previous version you were running. Seems like a much easier solution than the manual edited script and runs through the actual update process expected by the plugin.
