Defective autosave
Hello, I'm a Brazilian user and I have a problem with the projects I made: I have 3 projects in total, and I changed all of them today, in the late morning and early afternoon. As I was using it online, it doesn't have a save button, it's an automatic process of every 2 seconds the system saves itself. But it's been a long time since I finished changing, I waited the necessary time and decided to download the 3 projects to see the program that installs on the computer. But when I open the projects, none of them have the changes I made today.

I'm afraid of losing the changes that took me a few minutes to make, so I have all 3 projects open in the browser

I suggest having a save button even when we use it online

Re: Defective autosave
You might have encountered the same issue as in the bug #1075.
First, be sure that the auto save is probably the best solution in a JavaScript environment where a crash with a page reload may occur at any moment when resources are missing. I see from the server logs that the exports you obtain from your 3 projects contain the last changes received by the server.

But let's try to understand why the server didn't receive the last changes you made. I hope you kept the windows of your 3 projects opened (or at least one), so you can report what the content of the JavaScript console.
Display it by choosing the menu item More tools > Developer tools (Ctrl+Shift+I) and select the Console tab. The Console should contain some lines stating

Failed to load resource: the server responded with a status of 404 (Not Found)

and if it contains some other texts, please copy-paste it here because it could explain what's going on.

Re: Defective autosave
Hi,
I still keep the 3 projects open and I still have the same problem of not saving what I changed - when downloading the file

This is what appears in one of the projects:

Re: Defective autosave
Yes I use ad blockers but this has never happened before

Re: Defective autosave
As I will need to turn off my computer now, when I turn it on tomorrow, probably the 3 tabs where the projects are will update and I will lose everything I changed today T_T

Re: Defective autosave
Unfortunately, the Console text you reported doesn't help.
I hope that you'll have the patience to run more tests. If this keeps happening, I'll try to change the program to inform the user when recent changes couldn't be saved.

Re: Defective autosave
I just turned on my computer, and as expected, none of the 3 projects were saved, I'll have to redo everything T_T

For these reasons and others, I believe that having a save button - so as not to depend only on automatic - would be another layer of security to protect our projects from some bug, like this one that is happening

Re: Defective autosave
I need more feedback before considering developing such a feature. Tracking an automatic saving operation during the last minutes didnâ€™t happen will be easier to program.
By the way, even if itâ€™s sad that you lost some time, donâ€™t let others think you lost all you work. From the logs records, you seem to have lost 2 hours of work at worst.

Re: Defective autosave
Well, what can I do... I'm redoing everything, but also including new stuff. I hope you save this time

Re: Defective autosave
Then check regularly that everything is saved by reloading the page, because Domenico Melisi reported this issue happened repeatedly in his case.
