Intellij deleted all my modules and files after recreating top-level module in nested-module project!

Fortunately my project was pushed to github, so I didn't lose much.

I re-created the top-level module, and all existing files, modules including .git were wiped out!

Here are the steps to recreate:

1.  Create a Project called “top-level”, say HTML.   Location:  /tmp

2.  Creation a new Module called “java” as Java module, Location:  /tmp/top-level

3.   Create a few files in /tmp/top-level.   `touch one.txt two.txt three.txt` or whatever.

4.  Open Module structure, cmd-; then delete the module “top-level”.

Note the module “java” is still in the project, and no files have been touch including step 3 files.

5.  This is where it goes wrong.  Attempt to recreate the “top-level” module with New Module, HTML, name “top-level”, location: /tmp/top-level.

6.   The Module “java” is deleted from disk.   /tmp/top-level/java is gone.   /tmp/top-level/one.txt etc. are gone

It's as if an entirely new Project was created, rather than just adding a new Module
