My situation is a little weird from what I've seen on the forum and from googling.
Mac OSX 10.10.3 (Yosemite)
Jonah format in Twine
Tested the game just fine in Google Chrome
I started writing my game in Twine and got a ways into it, then had to stop for the day. I Saved As, titled the game, clicked save, saw that the file had populated the folder I wanted it in, and then quit Twine.
Later, I double-clicked the .tws file. When Twine opened, it gave me a blank story with the title of an old, discarded game I had done several months ago, but with no content. I deleted that old, empty story from my files and then tried to open my current .tws file. Twine then gave me a brand new "Untitled Story."
Every time I tried to open it, I got a blank, new story.
Wha? Where's all the work I put into it? Did I mess up somehow?
