I am new, so I just drove my second day, had a few points (ca 163 or so) and found a few goodies. I also reported one map-problem and a road name.
But just now, while I was logged in I was browsing, and suddenly waze wanted a new login, which worked, but now my stats are all 0, my rank dropped by 38xx and my recent driven routes went away.
What happened? It was all there 10 minutes ago?
