We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
Ok. It actually worked fine, and did say Done!, but I checked and I removed it duplicating at top (above files) and bottom. But I should have removed it from Top, not from Bottom. Fixed.
Confirmed on wwsu1069.org . Again, done! appears at the top and not the bottom. However, it may be because 10RC19 has the fix, but obviously the fix is not applied until after the upgrader completes.
