I have just been rendering the tile with a current _unstable to see if it is indeed fixed:

http://tah.openstreetmap.org/Browse/?layer=captionless&z=12&x=3713&y=2264

It is empty land, though in the middle in the sea and I first suspected a client error. However checking oceantiles.dat shows:

spaetz at hal:~/src/tilesAtHome_unstable/tools/png2tileinfo$ perl png2tileinfo.pl check 3713 2264
oceantiles_12.png(3713, 2264) = 1 (land)

that it is indeed marked as land, so the client is right here. yay!

I have marked the tile in question as sea now in oceantiles dat and requested a rerendering.

All is well...
