If you’re playing Modern Warfare 3 on PC and have been playing through the campaign, there’s a good chance you encountered the “reliable command buffer overflow” error in the mission Goalpost. It sucks, doesn’t it? Well, one helpful Call of Duty forum member has figured out how to avoid this error. He said this:
The solution is not to go along the street but jump inside the bulding with broken windows on the right. There will be several enemies there, you will kill them, exit the building on the other side and the checkpoint will save. Going along the street in the open causes this glitch.
Our bro Ron has tried this and confirmed that it work, so just do what the good man says and you’ll be on your way to winning the war and having fun again. Yay fun!
