Graph not updating on Tor 0.3.4.0-alpha-dev

I decided to test out git version of Tor (Tor version 0.3.4.0-alpha-dev (git-382beb93cb4110b2)).

After the upgrade, the nyx graph no longer updates at all. It's all blank. Affects not only the bandwidth graph but it doesn't work on "resources" or "connections" either.

It was working fine on Tor 0.3.3.5-rc.

I have nyx 2.0.4 and Python 2.7.15
