Lost all of my work

I don’t know if this is the right area to post this, but I was opening my file(the thumbnail showed I was right where I left off) and when it opened it was completely empty and lost all the work I’ve been doing for the past week. Is there any way to fix this?

Make backup copies next time , the whole point of source control is just that. but what you describe seems rather impossible without some very serious glitch or human intervention either intentionally or unintentionally

i got something similar, but my whole project folder dissapeared.
maybe try the auto-saves unreal makes.
they should be in your project folder (C:/Users/[Username]/Documents/Unreal Projects/[ProjectName]/Saves)
dont quite know exaclty how to but you can maybe recover something from there.

Sorry to hear about your loss.

When using any game engine and 3D art package, you need to use version control and regularly commit your changes, it can just be a local svn on your computer if you don’t like git or perforce, but it will save you so much time and headaches.
