I have used Power Auras for a long time to keep track of my Hot Streak/free Pyro.
For some reason, since the last couple of days it has stopped working. I also could not find a new version in curse. So I am looking for an alternative.
power auras classic has worked great for me, i just re-installed it after the patch and everything is fine. just uninstall it and re-install it, that should fix the issues you're having.
