Every now and than the IDEA based GoLand JetBrains IDE refuses to work along side with Node.js (react/redux/JS) based applications.
The problem looks like this:
When you change something, the file is marked orange which kind of suggests, that the file is in undefined state (as far as I remember).
The file is not listed as changed in the Version Control, you need to hit refresh:
After refresh, the file is in defined state again and: the file is also listed as blue (changed)
But what is the reason for this issue, it should not need manual refresh all the time!
