The main body of an article that I could open and edit yesterday now comes up blank when I try to open it today. There's absolutely nothing in the text editor.
This is an article I've slowly been working on over a long time, but everything has been deleted, not just what I added yesterday.

I am truly sorry to hear that EpicWalrus (What an amazing nickname)
Sadly, we cannot do anything about this with very little information to go on to. In most cases, and by more I mean 99% of them, this meant that you had the article open on another tab, and on that tab you had a previous version that somehow you saved at a later time.
We are actively working to find ways to prevent part of this happening but it is true that working on multiple tabs is indeed very dangerous and you should try to at least minimize it.
