Hi all. Technically not really an EMC problem perhaps. But a problem specific to EMC.Using mod: World Downloader for minecraft 1.7.2I download my overworld areas just fine. But in the nether, some areas are not downloading. I click download world, then move around to get all the bits I need, then stop download (and download world again, due to a bug with 1.7.2 world downloader it doesn't save until you start download again). It says 'still saving' and never ever stops.The region files I get if i just disconnect, are incomplete, missing in particular the areas of the world I have modified.Any have this issue? And anyone know how to fix it? (only seems to happen to me in the nether).
