• VSCode Version: 1.8.0
• OS Version: Mac OS X El Capitan

This issue seems to happen only for mounted drives (e.g. SSHFS a remote server to access files, and open the mounted folder with VSC).

Steps to Reproduce:

1. Open Visual Studio Code with the folder of the mounted drive.
2. Edit and save a file (unfortunately, I can I only get this to happen sporadically. Sometimes it works, sometimes it doesn't... and I can't seem to find a pattern for it)
3. The following error messages show up:
   "Failed to save 'examplefile.js': The content on disk is newer. Click on Compare to compare your version with the one on disk."

And then when I click "Compare":
"Unable to open 'examplefile.js (on disk) ↔ examplefile.js (in Visual Studio Code)': Could not resolve any model with provided uri.."

I hope this was helpful, and if there is currently any resolution to this, I would like to know. It has only been happening since I updated to 1.8.0. It has made VSC unusable for me on my current project (and I really love VSC, its been great).

EDIT: I included a couple of screenshots. It seems to happen with any type of files, but I gave this one as an example.
