I've been working for a client site and I have problem with rendering of Roboto font.

In Chrome (ver. 43.0.2357.65 m) all the various weights of Roboto looks same.

Well, it's such a shame, but I have had old version of Roboto installed on my PC.
Since I deleted, everything works fine again.

I should facepalm myself hard..
