I've created a fork of my codebase and began working on it.
When I hit Deploy, it ran and then everything in the preview to codebase and directory structure as well as project settings have disappeared. The panel says Untitled. All I've got left is the chat prompts.

The deployed code didn't get absorbed into my project (it shows the previous fork). It's happened on Safari and Firefox in the last 12 hours. Two weeks ago, it happened on Chrome.
The amount of rework I've had to do is frustrating. And no, I didn't back it up to Github! :(
Has this got to do with cache or cookie settings for privacy?
