Running 188.8.131.52 on my Dinc, and I'm seeing a behavior I've seen on the 1.9 & 1.10.xx clients.
Sometimes, when I munch a new neighborhood, I'll drive the road parallel to the one I was just on (head East on "A", turn South on "1st" one block, head back West on "B"), and the 1st road ("A") shows unmunched. If I go around the block and drive "A" again, it shows me munching again. I seem to collect point for it both times, but there's no real way of knowing (that I can tell), so it works nicely that way, but it is frustrating to have to drive some sections of road 2-3 times.
I've also noticed that sometimes, it'll show munched today, but when I drive by tomorrow, it'll show unmunched again.
This is the client that's showing this, and I'd think it'd have the most current data. I can usually go see my tracks in Update mode the next day, but the client may still be showing it as unmunched.
