I’ve spent the past 3 hours importing some of my assets into my project. Every couple of minutes UE4 would start to autosave all the textures and models I imported. When I tried to build the level it crashed. I’ve gone back into my level and it had not saved anything.
Are you using any software like perforce for version control?
I have now found the Autosave folder, and I don’t think. Never heard of it
