Siri failed after update

After updating to the latest Indigo Siri started to act weird. (might be unrelated though)

She didn't understand phrases she used to. When saying "turn on kitchen light" she turned on all lights - always. Sometimes she refuses to understand living room, although she clearly recognizes my command. The biggest issue was that instead of starting a scene or turning on a virtual device she opened my garage door. Again this happened always and was not the result of misunderstanding my command.

After I set up a new user in the config.plist everything works again.

What did not work prior this:
restarting Indigo
restarting Homebridge
updating Homebridge
restarting iPhone, including Apple TV and all iOS devices

I just wanted to let anyone know that there might be an issue (Apple, Indigo, or something else).
