Tile cache polluted with garbage data in connection with Osmapa.pl faults
Recently, the Osmapa.pl tile server is facing issues again, some zoom levels are not loading at all. Okay, I've already got used to that it is quite unstable, but I found Locus doing a nasty thing about it. In the case of tiles that could not be downloaded, it clutters the tile cache with garbage data (1 byte image blobs), which means that until the expiry of these garbage entries, it will not retry to download these tiles next time. What's worse, if the cache already contains downloaded correctly tile in the past, and when Locus tries to refresh it and fails, it overwrites it with a garbage entry. Is this how it should work?
