Lost Scene would apreaciate help.

Hello everyone.

I was working today on my project and i got a huge problem, one of my scenes now is a copy from another one, i havent opened my scene since yesterday, and it was perfectly working, but today i open it and it shows like if it was another scene.

Anyone knows something about this issue? i already uninstalled unity and reinstalled and the problem persist what could i do? i cant lose that scene is an entire stage :(.

Are you sure you don’t have multiple scenes open at the same time?

Or do you ever do “Save Scene As” when saving scenes, which would make it possible you accidentally saved over the wrong scene? If so, I hope you have a recent backup of your lost scene.
