My directory structure in the Project seems to have disappeared. The first picture is the "bad". I recently upgraded to 12.1 and the vim emulator at about the same time. I don't know if I missed a dialog that reset something? I can't figure out how to get it back like the second picture.
I've tried to re-import the project but it has not helped. I keep the project on Dropbox and have another PC where I have not reloaded project. Is there a way to get my view from that machine?
The picture is the "good" and how I want it to look.
I've come across this problem a few times myself. What happened is that intellij lost the module in my project settings. Here's my steps to fix it:
File -> Project Structure -> Click on modules (notice empty list) -> Click on '+' -> Click on import module -> Find existing myProj.iml
