title: Praw Python doesn`t show every submission from a subreddit
body: <pre><code> def get_submissions(self):
          for submission in self.reddit.subreddit("all").new(limit=None):
              self.submissions.append(submission.title)
          print(self.submissions,len(self.submissions))
  </code></pre>
  
  <p>This is my code. I am trying to get all submissions from a subreddit, but somehow, it stops at a certain value. I am trying to build a statistic over a subreddit, and I kinda need to fetch a big amount of posts, more than 2000, maybe. But this method gives me everytime &lt;870 posts.</p>
  
  <p>Do you guys know a solution for this?</p>
