everything in my hierarchy is gone.

So I was working on a project in untiy and then, after I was done for the day, I saved and closed the project. However, today, when I opened it, all of the objects in the hierarchy were gone. I have no idea why this happened. and judging from the file of the project, it wasn't edited or anything, since the 'last modified' date is yesterday, when I saved my project. Please help me with this; if this is a problem with the engine, this needs to be fixed, as this has weeks, even months of work.
I understand that I should have made a lot of backups, but it isn't something I have been doing routinely and I need a solution, rather than a way or prevention, at this very moment.

 

Load a scene. A project doesn't contain any hierarchy; scenes do. And yes, you need to use source control or at least make backups...it's not optional, ever, if you care at all about your data.

I meant the scene doesn't have any gameobjects. Is there a solution to this?

 

Are you sure you loaded a scene? Scenes and projects are quite different things.

Same thing happened to me. Its really depressing

 

same thing happened to me, loaded the project, everything in the hierarchy was gone. Eric5h5's suggestion of loading a scene fixed it

 

same here, i just loaded the scene in the scenes folder in the assets category.

 

I'm sorry you've had this issue. Please consider using proper industrial-grade enterprise-qualified source control in order to guard and protect your hard-earned work.

Personally I use git (completely outside of Unity) because it is free and there are tons of tutorials out there to help you set it up as well as free places to host your repo (BitBucket, Github, Gitlab, etc.).

You can also push git repositories to other drives: thumb drives, USB drives, network drives, etc., effectively putting a complete copy of the repository there.

As far as configuring Unity to play nice with git, keep this in mind:

It is only simple economics that you must expend as much effort into backing it up as you feel the work is worth in the first place. Digital storage is so unbelievably cheap today that you can buy gigabytes of flash drive storage for about the price of a cup of coffee. It's simply ridiculous not to back up.
