During the most recent test, I noticed a couple of odd behaviors on street projects. They might be related. The first is that the animated progress indicator (the pick picking, the globe rotating, whatever) continues to indicate progress but the numeric indicators do not increase,and trying to cancel or close out of this state results in the message "Can't cancel" (I believe) and indeed it doesn't. The second issue is that, when this happens, I am apparently making no progress on the street project. When I (finally) cancel out of the street project and re-enter it, my impression is that I have not been credited with any contribution since no progress was indicated.
