I'm using Twine 2.1.3 on Mac OSX.
I completed the first version of my game, and successfully "Publish to File"d it.
I then created a duplicate with a different name, changed some code, and attempted to do the same. However, when I click "Publish to File" no dialogue box appears.
Also, "View Proofing Copy" produces a white screen.
Both functions work fine in the original version of the game.
I tried restarting my computer, but that hasn't affected the issue.
Can anyone help?
