Invalid Project File Error

Hey everyone,

I saved my project file in the latest beta release a couple hours ago and now the project file won't open and is reporting as an invalid project file. This has happened to me a few times now and usually I can figure it out by looking at the console errors and editing the extracted JSON but this time I can't make heads or tails of the errors. Any ideas?

To add a detail, I can still open earlier versions of my file from yesterday and before as well as any of the sample files. Its just the two project files that I saved today that are affected.

dop2000 I tried your experiment and I was able to open an earlier version of the file in the latest beta, save it as a new file, close it and re-open it.

I have already tried clearing all browsing/cache cookie data. And as another note, I do remember yesterday that Construct was being finicky when saving. I had both affected project files open and I had to click save several times on each project in order for the save icon to deselect and construct to allow me to close without giving me the "leave without saving changes alert".

I appreciate the help. One of the affected files has virtually no changes from the previous version, but the other has 3 days worth of particularly tedious work that I'd really rather not lose.

Oh, and the only add on in the project is Overboy's Dictionary Behavior, but I didn't update it recently, and it's not in use on any objects, it's just added as a project behavior.

dop2000 any other suggestions?

This actually has been happening for me in the past few days - the save icon stays active for about 20-40 seconds after saving. Maybe the fact that you clicked it multiple times broke something in the project..

You can try sending the project to Construct support email. Don't forget to attach all used addons.

I have the same issue, reported here: https://github.com/Scirra/Construct-bugs/issues/8576 and I also sent an affected project to Ash.

Ok, thanks both of you for responding, and thanks for submitting that bug report — I see both your responses on Discord as well. It sounds like this is all connected, the prolonged saving and the file corruption. What's weird is the corruption of the saving seems to have been within a limited time period for me. The auto save and and the manual save at the time both got corrupted but the next day when dop2000 asked me to try opening a working version and saving then I was able to open the newly saved file. I just tried again and confirmed that I can save and re-open working files. Why would this only affect that period, at least a 20 min period, where it would corrupt both the auto save and the manual save? Very strange.

For anyone finding this and having the same problem, see this github bug report: github.com/Scirra/Construct-bugs/issues/8576.

I have applied the edits recommended by Scirra and was able to successfully open my project. If you don't know how to edit project JSON's from outside the app, post here and I'll walk you through it.
