--Issue Summary--

context: https://discuss.pencil2d.org/t/help-my-animation-is-corrupted-i-need-help/2540/6

The user had been working on an animation over the course of a month when it suddenly stopped working.

having investigated the project file which was provided to me in a private message, all content is still there except the main .xml file. This suggests that the file has been deleted from both the temporary folder and saved project file, rendering it impossible to open again.
