Yesterday, my game crashed, when I restarted the game the launcher started validating the files but only for 39Gb+ I was wondering why not all of them but then I noticed it started redownloading them I was annoyed but then I said as long as the game start again I'm fine. Couple hours after, another patch was downloading then another and another. Currently I lost track of how many patches has been download it, I made a mistake but closing my PC at night I didn't expect all these files to be downloaded.
My question is that normal? Did the launcher redownload the entire game? and if so why is the files are put in different patch?
The most important question is validating the files actually? works from what I experienced it looked like the game when validating files compare them to the original games files that should have been patched for years if so validating the game actually mean re-downloading it?
