You can't expect too much from the staff, they are already all doing voluntery work and some are even spending money on it so that WE can all play for free. It is real that some people will get angry because they "wasted" some bandwidth, but luckily, we have something called the "updated". It will download only the things which need to be downloaded so that we don't need to download a second time the things we already have on the computer.
I heard that they will be many new textures and the map have changed, this would mean that the heavy things will be to download again, but you should still save some bandwidth.
What I mean by that is that the people who download version 0.3.014b didn't waist they bandwidth because they will be able to update they version to 0.3.015 without using too much bandwidth

Restore, please BE PATIENT!!! Stop complaining, you are playing at a totally free game which is run at the expense of the DEVs, so the least you can do for them is to stop comlaining all the time
