Hey guys, just updated today to 0.5.1. "Core-animations" is importing "web-animations.html" which is importing "../web-animations-next/web-animations.html". The problem is that the file in the "web-animations-next" directory is currently named "web-animations-next.dev.html".
This is throwing all kinds of errors and freezing the browser on load. I tried to find the web-animations-next repo to file an issue but didn't see it in the Polymer org.
