Hi,
I may have discovered a bug that causes lost data. Here’s how to reproduce it.

Sublime Text 3 Build 3059

• Choose 2-column layout

• Open an existing file (say, a.txt) in right column, and edit the file. Don’t save it.

• Create new file in left column

• Save file in left column as a.txt, overwriting the original a.txt

• Both columns will now contain a.txt, but the contents will be the modified original a.txt from the right column, rather than the new a.txt from the left column
