A custom field with " Display When Resolving Issues" but not "Require When Resolving Issues" is not stored into the database!

Possibly this patch introduced the bug, because in prior versions of bugupdate there was also something written about update $t_custom_status_label.

bug_update.php v1.85 L 96:

Only update the field if it would have been display for editing
    if( !( ( ! $f_update_mode && $t_def['require_' . $t_custom_status_label] ) ||
                    ( $f_update_mode && $t_def['display_update'] ) ||
                    ( $f_update_mode && $t_def['require_update'] ) ) ) {
        continue;
    }
