[Tilesathome] Unnecessary re-rendering of tiles?

[Rob Reid]

This was discussed briefly on irc the other day but I'm not sure any 
conclusion was reached.

I'm looking a tile that was rendered a few days ago when I changed the 
data and it's status seems a little strange.
The tile is http://tah.openstreetmap.org/Tiles/info.php?x=4011&y=2595&z=12
(Note that the status may be different by the time you read this email 
as I have made changes and am going to re-render it)

Currently the tile info shows


        Current Request Status

    Requested at 2008-02-01 18:39:07, by server:MissingTile:7, with
    priority 3.
    Current state is *Pending*.


        Tile on disk

    4011,2595 at z-12 is blank land, uploaded by user 215

My question is why has it been flagged as MissingTile when there is a 
valid and current tile on disk?
The suggestion on irc was that it may have something to do with the 
blank tile reducing process?

Cheers
