Just got this message for a number of translations, all rather long pages, which I had been working on for several days.
Don't tell me all this work had been for nothing.
Edit: Okay, seem to be loading now. Would be nice if you could save intermediate versions on your personal user page (without the program deciding it's published and finished)
Edit: Whatever. Seems I was just very lucky to get that last one back, but a number of other pages still won't load.
Edit: This is getting silly. It now gives this message for translations I have not even started.
Edit: At ths point, I can only advise anyone that, after starting a translation, DO NOT CLOSE THE WINDOW if you do not have to.
