[Tilesathome] white hole on the Canary Islands

[Raphael Studer]

Hi,

I've drawn the coastline around some Islands of the Canary Islands
(ES) in the past month and added them to the new lowzoom queue
yesterday.

Today the whole area looks very strange:

There is a big white hole around Gran Canaria, an other island is missing.

There are also some Land Tiles on the bottom of an other island (been
there some years ago but forgotten the name)

I'm shure I have removed them (pressing s while tile is selected on
ifw.org) a month ago, and there has been see last week.

Any ideas why this happens?

Regards

Raphael
