Alright, some conclusions for today. First of all, client starts throwing some errors about trees. If it means that I accidentally messed git repository, I'm sorry
Secondly, git may be useful for the source code, but it's totally unacceptable for content.
For testing purposes today I downloaded distributive ten times, and only two times it was successful.
Obviously, hereinafter the larger will be the size of the content, the smaller will be the chance to download it. We have to use anything else, like db, mega, maybe torrent after the game release.
