Apparently, as I read in the talk mailing list a day or two ago, Pokemon Go is now using OSM maps for its display since two or three days.
That means that if their previous map was something else as it apparently was, users will notice and report on the changes as missing/removed/misplaced things.
I think many similar reports as well as other Pokemon-related park/water notices will be appearing more frequently now :-/
I asked in another such report for clarification, we will see if my suspicions are correct there.
