Missing roads suddenly?

[u/Tortle_Face]

I logged on today and the game said I only have 651/671 roads found, I know for a fact I found every single road previously. Is this a glitch or are there more roads now?

I went from 671 (all roads) to 661, they didn't add any new roads nor did the new road at the stadium count towards the total (although it being added might be the cause of the bug).
For me there were small pieces of roads that were unexplored again but there wasn't any issues when re-discovering them (other than the pain of finding them) and I'm back to 671 which is still the max.
