I confirm the existence of this bug. At first I thought it was my bad but then I got suspicious and decided to check the forum.
I think it was version 0.11.0 or 0.11.1 - the one that was the latest for the 13th of February. I was on a long flight with no Internet access, was working on a large file (around 15 KB) when suddenly my laptop’s battery ran out.
Back on the ground I checked the file that I worked on, it had my 15 KB of text all replaced with \u0. Since the file was created on a plane, no cloud copies remained.
Please look into this issue ASAP. Very dangerous stuff, several hours of work lost.
