Chatbot don't answer to direct messages in the version 3.3.3

I updated my RocketChat server from 3.0.12 to 3.3.3.
After the update, the chatbot stopped to answer direct messages (DM).
I did a bunch of tests and discovered that:

  1. the problem doesn’t happen on the previous version available at DockerHub (the chatbot remains working on 3.012 and 3.2.2 versions)
  2. if I set a word trigger in the Rocket’s outgoing integration, the bot answer again at the 3.3.3 version.
  3. I avoided the problem by manually downgrading to version 3.2.2

Before opening an issue at Github, I’d like to know if this is a problem for someone else besides me.
