Changing files with git could have changed many project files... But it is strange, I make modifications very rarely and most often one by one for commits. And never on all projects on the same time, because one just have no dependencies on other nor other's dependencies, and is pretty stable.
But I have many projects in the workspace:
_ the main application
_ a render engine
_ a plugin engine
_ 2 plugins
Plugins are just for tests and when plugin engine is modified, they are often modified too, as the main application (and I am currently working on that point because plugin engine is just crap. I am ashamed of it's code)
So maybe a modification had made me modify many projects and the git cancel those modifications?
Anyway, it is not a big problem, it only happens rarely, and I am not even able to reproduce it easily. Just a kind of notification in fact.
PS: just a note: about the " this is also something you should not do " imagine you are working on a netbook and reload a workspace after each commit/checkout is not really fast
