I went to patch my game to the 1.1.4 which was a 4gb patch (why is it that big to begin with!?) and left my PC to do its thing. Came back when it was due and now the patch has grown to 12.5gb???

Wtf!? Im now going to use half of my data (thanks Australia) "patching" this game when its clearly just reinstalling it.

Has anyone else run into this problem?
A 10 minute patch has now turned into a 50 minute installation and i dont think im going to be playing tonight. Very pissed off.
