For all we know the file that house major things like the Market Wards and Combat have to be redownloaded each time a minor edit is made to them because of encryption.
Actually Viion has proved that each update in 1.17, 1.17a, 1.17b, 1.17c all contained exactly the same data + a little bit extra in this thread here:

Unless you have something to prove otherwise that we aren't re-downloading the same data over and over again then I will have to go with Viion on this one.
