I composed a fix for everyone. Hopefully should work for everyone like it did me.

When in doubt, leave it up to me to fix da bugs


If you don't wanna re-import the XML then goto your plugin manager

FIND: newthread_post_start

if($forms['required'] == 1)
    {
      if(empty($value))
      {
        eval(standard_error(fetch_error('fill_in_custom_thread_field')));
      }
    }

replace with:

if($forms['required'] == 1)
    {
      $forumids = explode(",", $forms['forumid']);
         if(in_array($foruminfo['forumid'], $forumids))
           {
      if(empty($value))
      {
        eval(standard_error(fetch_error('fill_in_custom_thread_field')));
      }
	   }
    }
