This has happened to me twice already. I couldn't figure out why my application was behaving like an older version until I realized that my code had reverted to the previous day's code. When I hit ctrl-z I received a message saying "Undo Revert" on the status bar and my latest code was restored. I don't know what caused my code to revert to the old saved version, but I don't like this one bit. If I cant trust this with my code then I can't use this.
I am running on Windows, Version 2.0.1 (build 2217)
Here are my installed packages
"Theme - Soda"
I save my files all of the time. The last time I let my PC hibernate. I wonder if that has anything to do with it.
