I’m going CRAZY!!!
I just import a package from another collegue witch contains several scenes. But it turns out he have a scene with same name of one of mine. And after importing, my scene is overwritten by his!!!WTF.

I tried ctrl + z, but not working. So I just close the project without saving. And when I reopen it it seems my scene will gone forerver. There’s no deleted scene file in garbage neither. Errrrrr, The Entired Scene Of Mine is GONE!!! I don’t want to go through it again!!!

I notice the odd thing is the last change time of my scene file is realy far away, while the meta file has changed just now. I’m wondering Where The H Unity stores my scene data!

Is it possible to get it back? Plz Help me out of this Plz.

I think we all suspect that you don’t have backups or version control set up. As Graham Dunnett writes, don’t bother trying to rescue the scene from your project. It’s gone.

Have you sent any packages to your colleague that might contain the original scene? Perhaps you could find a copy in your sent mail.

For the future, here are some helpful links to set up version control:
