Plugin forced NodeBB to crash / restart - 3 times in a row

[GitPuffy]

This plugin works great, when it is working and works for periods of time without difficulties. Occasionally it throws fits. Recently the twitch-plugin caused my NodeBB to crash and restart three times in a row. I had logging enabled in my tmux session so I have the luxury of posting the crash / start messages. I am running NodeBB v1.0.2 and nodebb-plugin-ns-twitch-monitor version 3.0.4.

These are the errors:

If you used a twitch-monitor before v3.0.4 Try to re-install plugin from the scratch, I mean delete plugin data from the database. More details could be found on NodeBB forum in corresponding thread.

Re-open a ticket if plugin data removal doesn't help.
