Infinity Ward rolled out a server-side update for Call of Duty: Modern Warfare yesterday, zapping a few bugs but causing the game to throw up error 656448 for players across all platforms. Soon after the update went live, the game?s subreddit saw players complaining that their Modern Warfare profiles were not being fetched, and instead, they were being disconnected.

.defineSizeMapping(standAloneSizeMapping) .addService(googletag.pubads())
