Feedback Case Number: 57884
Autorecovery of unsaved project files after an IDE crash was lost with 2019r2.
It is now missing for more than one year as I just experienced with 2020r2.
I feel this is a serious regression and wish that the ticket would get some attention soon.
Jesus saves. Always.
Obviously he will be the only saviour. One year later, no change. Like just experienced. 
Same here on Windows 10
I wouldn’t mind seeing some auto-save features in the future, or auto-save when clicking the run option to debug your app… That would be awesome! 
This is literally one line of code:
DoCommand "SaveFile"
Forgive me… I’m new here… But where can I do that DoCommand? I want the IDE to save my work for me. Is there something I can setup to do that based on what you sent with the DoCommand “SaveFile” ??
Ok, this has just opened a whole new can of worms for me… I just found IDE Scripting window and I’m now reading docs on this. I’m scared!
I got a T-Shirt like this…
You can do a lot with IDE scripting. My main app has a dozen IDE scripts. And then there is the IDE communicator for building multiple apps.
Real men/women don’t do backups.
But for that they cry very often. 
Yea, I’m finishing up on the Webinar that Xojo did back in 2014 about the IDE Scripting. How after 2 months am I just finding out about this?? lol
So just to update you: Yes, IDE commands can be quite handy. I usually do not want to save every test code I write, and Xojo used to be quite stable until 2019r2 when it lost its AutoRecovery feature. That meant the IDE noticed it had crashed and offered to reconstruct the latest version – at maximum you lost a few lines of code. And if that did not work, you could close the project and reload it from the latest intentional save.
According to @Greg_O_Lone, this regression was fixed in March this year but was never verified and did not make its way into a release. Because the case was closed already, it maybe never will if not reinspected.
