Hubot heroku multiple dyno

[ap13p]

Hi, sorry if this already submitted before.
But, when I deploy hubot in heroku with 2 dynos, hubot will response / send message twice instead of 1

Unfortunately, there are some limitations in how hubot currently works that will prevent hubot for working with multiple dynos. For now, decrease back to 1 dyno, and we can add some documentation around it.
