Downloading the entire game again for one patch. This is getting really old, especially since the Galaxy client offers no way to throttle bandwidth. The entire internet connection becomes basically unusable when Galaxy is downloading anything.
What version of the game were you on before you started downloading?
Also, may I ask as to how you start the download process? Do you let the game update naturally or are you running a "Verify & repair" check?
Basically, if we could get some steps to reproduce from those of you who get the 13 GB download issue, it would help to narrow this issue down..
I update my games automatically through galaxy. Right now (latest patch) Shadow warrior 2 is downloading all over againg... Very "uncommon" to say the least
