I may have fucked up

I implemented a new Main Menu that starts the game and quits. I started working on a pause menu but did not get to finish it before I destroyed everything.

I reorganized the folders in my project, and through my lack of understanding of unreal a majority of my level ended up unloaded. I spent 30 minutes attempting to fix it, and my solutions instead deleted all unloaded assets. I then gave up on the project, so it's dead. I can't say I spent very much time mourning,  but it is a shame that it's gone.
