Potential regression for c# autocomplete

It looks like the autocomplete/intellisense functionality is no longer working for c#.
Method/variable names no longer auto complete, also pressing Ctrl + space brings up “no default proposals” message. I get this issue with the latest versions of chrome and firefox. (I just tested clojure and that seems to work fine)

Also I just wanted to say, great job on the site; its a lot of fun.
