Git local changes bug (keeps forgetting changes) in multi-modules project


Since IDEA 13 came out, multi-module projects that we upgraded from IDEA 11 keep forgetting changes whenever we change to another application and then back again.  This happens on different projects, on Windows, Linux, and Mac systems with IntelliJ.  It doesn't happen on single module projects.

I'm following on from the announcement:

...inviting discussion, and it's a shame this is still broken.
