Projects for new streets typically include a grayed-out version of the new street while the project is in progress. Since I updated to the debug version of the flashplayer, I do not see these streets. Several other players also said they had the same problem. It may be due to the cache not updating quickly, or perhaps there is some other issue.
I'm using Chrome, and have reproduced the problem also with FF.
To see this:
1. Install the debug version of flashplayer appropriate for your browser.
2. Go to a map that has an active project. (currently Muufo has one).
3. Check whether the new street appears on the map.
Results:
The new street is not visible.
Expected:
A grayed-out street indicating that there is an active project on an adjacent street.
