this big ouch happened and the only way to rescue what you wrote is by recording your http headers and slurping the text data back out. It'd be cool if whats in the editor were archived in browser in events like this. First time it's happened to me, but kinda sucks if you're writing something large

that happens after 15 minutes of loading the postong page because of the csrf check, although it disposing your text is something that shouldn't happen at all so that's gonna get a fix
thanks for reporting this!

Fixed this along with a global token lifetime extension from 15 minutes to 30 minutes.
