So, Once upon a time, I found an update for the launcher. I clicked the link. I got the new launcher and renamed it to "Aether II.jar". I was expecting to see my world in the menu, but no. It was not there.
I was very confused. I checked my AppSupport file to look for the old folder. It was renamed "aether_old". I checked it, and the world was there. I was very confused.
"If the world is here, why can't I see it on the menu?" I thought to myself. It turns out, there was a new folder named "aether". When I checked it, there was no saves folder to copy the world to. When I made a world, there was still no saves folder.
This is madness. Help me in this international crisis.
