I don’t think it’s actually possible to make a game using blueprints.
Doing even simple things keeps leading to project corruption. I post and ask how to fix it and no one knows so no one responds.
Last night my project corrupted, mostly through my own fault with over-zealous deleting. Today I tried to reconstruct everything from scratch and it took ages, I was at the last step.
I moved two blueprints into a folder a directory below. Project is now corrupted again.
So, how do you recover a project ruined by a corrupt blueprint? Not a specific one, but in general.
