What do I do if my Apps Script didn’t save?

I was working on an apps script with a personal account. I clearly remember saving it, however when I looked back the next day, all the progress I made was gone. I deployed it once around 30 min in and that deployment’s code is still there in the version history. After that, I just used test deployments to test all changes, and none of the changes were saved. I lost about 3 hours of javascript and would prefer to not have to rewrite it. Is there a way to get back the lost code? This happened around 3 days ago.

I was expecting for my code to save, but instead it didn’t.
