Re: [Flightgear-devel] [patch] fix FGNewCache to really delete old tiles

[till b. <bu...@bu...>]

hi curt,

i fear i'm not the right person to answer this. (at least not without doing 
some time-consuming research).

i don't *believe* the problem you describe could be related to the deletion of 
old tiles. what i can tell for sure is that the correct tiles get deleted. i 
had lots of debugging output in the code during testing.

could someone with more insight into ground cache comment on this?

thanks,

-till
