oh, yes, now that you mention it, we have seen a bunch of issues with chrome 43+, we have noticed that Chrome has issues with some of the minified files (basically, it fails when retrieving the files from cache)
we don't really know why, but we think it is related to size. what we have done in production is make sure that the minified files are smaller than 300K or so.
I am running 43.0.2357.65 beta (64-bit ) and I don't experience any of the errors you mention
@dmartinezg thank you for checking. Chrome 45 canary seems to work, so I'll keep using that; do you think that it's an issue with the build or the npm packages not being minified properly? I'd like to help debug if possible.
