Is there anything I can do to repair a project from r320?
Construct 420.2 tells me it's not a valid c3p project. It does open and run within 320.
The error in the browser console points to a problem with a PNG within the project (see below).
Opening the project file as a ZIP file, I checked all the PNGs within it - the problematic file exists, and can be opened without error, as do the rest of them. If it's useful, that PNG is the first file listed in the list of all PNGs.
Thank you for any help!
EDIT — It won't open in any version from r389 onward
