Seems like an old issue returning.
I have just notice it happens differently in master and on npmjs.org right now.
In my local it throws the error, logs me out, redirects to /login
On npmjs.org it only redirects me to /login but I still have but session but no edit took place.
I'm going to assume that, since this issue is, like, 2 years old, then it's okay to close it :-D (Yes? No?) Feel free to reopen if you disagree!!
I DISAGREE! (but you can go ahead a keep it closed).
lol, ok :-D
(I can see how maybe the notion that "it's 2 years old so let's close it" is disagreeable on principle, and on that I agree. But if the issue itself isn't a problem anymore, then yes, it should be closed regardless.)
