Thanks a lot for reporting this!  I've checked out the area.  Like you said, the picnic tabels are gone and the paths were off.  I've modified the map accordingly, see https://www.openstreetmap.org/changeset/89767994

If anything isn't quite clear, please feel free to open another note.  Or just edit the map, yourself.  It's open. Also, it's not rocket science and we're happy to help!  :-)
