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 usually go the verification route when forcing a "manual"
update, in spite of me having it set to auto-update, but still, I love having the ACTUAL
choice of manual vs steam's mandatory automatic updates!...Otherwise, it does it's job naturally for the most part; though, it does not match up with my account via web-browser.
