title: discord.js message.member always seems to be null
body: <p>I am using Discord.js and have a long running Discord bot that suddenly stopped working recently due to the message.member object always being null.</p>
  <p>For example:</p>
  <pre><code>if (message.channel.name.endsWith(&quot;channel-name&quot;)) {
    if (message.member.roles.has(admin_role)) {
      // do work
    }
  }
  </code></pre>
  <p>This is always yielding: TypeError: Cannot read property 'roles' of null</p>
  <p>This error is also happening everywhere in our codebase where we look at message.member.</p>
  <p>Even console logging the message object completely, we see for certain that the member property is null.</p>
  <p>Is there some error going on with Discord.js? Has something changed?</p>
