I wrote a rather long question, with a picture and paragraphs n shit. After I finished I didn't yet submit it but instead went on to see what I had in my notifications, leaving the yet to be submitted question in another tab. I then came back to it... and it said "an error occurred" and poof. Question gone.
That's fairly typical, MyTakes are saved as draft if you so desire, but I don't think questions are. I tend to copy them out on my phone too because Chrome process death tends to erase every content I write and it is very frustrating when that happens; this is why it would need an app.
