This issue is incredibly odd, and it annoyed me greatly. With a weak network and bad weather, it’s going to take me a good 5 days to redownload this game.
I have no idea how it occured, however. No errors or anything similar have popped up on my screen. I started up the launcher to patch and it merely started redownloading the entire darn game. (Unless the patch is so large that 5% = 1GB.)
Does anyone have any advice to offer on this issue?
