Bug fixing for no bug.

At first i thought my game had a bug, but now it's the second time the launcher does it. I am sure i have no bug in my game, the ping is good, the fps is good, the game launches and starts correctly, but for some reasons i don't know the launcher sends me to an older patch, what makes it even annoying is that it sends me to a very old patch that i have to download 1665 mb. please fix that problem.
