I have issues with saving my model in OMEdit.  First, it's annoying that I cannot save a model directly, I always have to go to the upper most package to save. 
But more severe is the fact that sometimes my changes are not saved at all.  I definity save them : no more asterix in the file name and no warning when I close OMEdit.  But when I open OMEdit again and load the model, my changes are gone.

Not always, sometimes it saves as expected.

Trying to track the bug:
- Could it be that models are not saved if they still contain errors of if they are not balanced?
- Or that changes directly in the text of the package are only saved when that package is saved, even if that does not actually save anything because there is a parent package that has to be saved?
