Codesandbox-client: Files Are Randomly Overwritten With Contents of Other Files When Saving

🐛 bug report

Description of the problem

While working with CodeSandbox, when switching between files in the file editor, sometimes it happens that the content of the file being switched to are replaced with the contents of the file that was previously open.

It seems to happen randomly, but frequently. I've observed the bug with Chrome 67 and Firefox 62, both on MacOS 10.13.6.

It may have something to do with saving the files using the “Save” button in the top menu, possibly in conjunction with Prettier, which I use frequently, invoked by keyboard shortcut.

I've uploaded a video that shows me reproducing the issue:

At 2:15, I hit the save button, at 2:18, the contents of App.js and Hello.js are suddenly identical.

How has this issue affected you? What are you trying to accomplish?

Since the code change cannot be undone, it makes it very hard and unnerving for me to work productively with CodeSandbox. I've resorted to downloading the code frequently to have a backup of my code when the bug happens.

Link to sandbox:

Here's a sandbox where the bug caused the code from one module to magically replace the code of two others, so that App.js, Hello.js and StartEditing.js all have the same contents:

Same issue for me. The most important feature is Save Files & its broken now. I used CodeSandBox sometime 12 hours ago but the new changes broke the Save Functionality. Can't do anything.
