I've just installed the game from Open Beta game client to default location (in Vista). After running the launcher, it deleted all files in the piggs directory and apparently is currently attempting to re-download them all
What is the reason for this behaviour? Those files ware already installed on my computer, right where they should be. It doesn't have to re-download them! I've had my friend download me the whole 7gigs of the client precisely to avoid downloading them myself
Yes, I'm sure. The /piggs directory in the installer and installed game look exactly the same, except for the file size - all files in installed game directory have size of 64 kB (except for those being downloaded by the launcher, or course).
