On 2.0.4, I have exported the property set created by a demo site content (MODx Sample Site beta by Splitting Red) and then try to import the same set via the Import tool. This fails however, just indicating it is "saving" without returning an error.
Does anyone have any idea why this may be? And could I suggest the import function has a graceful way to fail and return some kind of error? (I guess this should be a bug report or feature request.)
