Missing some countries polygons after import

Hello,

A few days ago I updated my database with the latest planet file. Everything looks ok but I'm missing the Russia entry in planet_osm_polygon.

It is found in both planet_osm_roads:

osm=>
osm=> select admin_level, name
osm-> from planet_osm_roads
osm-> where osm_id = -60189 and boundary = 'administrative'
osm-> limit 1;
 admin_level |  name
-------------+--------
 2           | Россия
(1 row)

and planet_osm_line:

osm=> select admin_level, name
osm-> from planet_osm_line
osm-> where osm_id = -60189 and boundary = 'administrative'
osm-> limit 1;
 admin_level |  name
-------------+--------
 2           | Россия
(1 row)

But not in planet_osm_polygon:

osm=> select admin_level, name
osm-> from planet_osm_polygon
osm-> where osm_id = -60189 and boundary = 'administrative'
osm-> limit 1;
 admin_level | name
-------------+------
(0 rows)

On my production server using an older planet.pbf file, it is in planet_osm_polygon as well.

What could be wrong?

Edit: I'm missing multiple other countries as well: Brazil, Argentina, Chile...
