 Ok, so shortly, custom theme has couple of page templates, all affecting
 pages only, located in theme template-parts folder (like _s structure).

 When I updated Wordpress to 4.9, I can't create page templates anymore,
 when I add page template, choose unique name, it doesn't show up on page
 templates list (as tho values, or list of files is cached somehow).

 When i rename template name in already existing page-template, it changes
 it properly in templates list (in page edit).

 But, when I rename page-template into (old name: template-example.php) for
 example: template-newexample.php, i get error:

 Warning: file_get_contents(/vagrant/wp-content/themes/mytheme/template-
 parts/template-example.php): failed to open stream: No such file or
 directory in /vagrant/wp-includes/class-wp-theme.php on line 1042

 as tho it is cached somewhere.
 This is happening when I try to rename any page template, not just certain
 one, and even if that page template isn't used anywhere, it still bugs out
