A bug/exploit has been a hot topic in the community of Call of Duty: Modern Warfare in recent hours. The developers responded quickly and fixed the issue.
What was the bug? Recently, CoD: MW was updated with Update 1.14 which was needed for Season 2. This update introduced a feature for regiments, essentially a clan system, into the game. Players could now change the color of the clan tags to their preference.
What was the problem? Due to a setting, it was possible to also color the displayed player name. This could make it appear blue all the time.
This meant that your opponents who exploited this could be seen with a blue name, making it easy to confuse them with allies. The bug turned enemies into friends.
For the community, this was a “gamebreaking bug” that quickly gained a lot of attention on Reddit.
How the developers responded: About three hours after this post was made on Reddit, Paul_Haile from Infinity Ward responded in the comments. In his reply, he agreed with a user that this is a gamebreaking bug that should be fixed immediately with a hotfix and added: “We are on it.”
Just under three hours later, he responded again in the comments on Reddit saying that it was indeed a bug. The ability for players to color their names was not intended. They wanted to ensure that clan tags exploiting this would be corrected and also announced additional protective measures so that regiments with invalid characters could not be created further.
It became clear that Infinity Ward recognized the negative impacts of this exploit and acted immediately instead of waiting until after the weekend. In just a few hours, they had devised a solution and implemented it. This doesn’t happen so smoothly in every game.

The bug status could be tracked on the Infinity Ward Trello board.
The humor the developers employed in the Valentine’s Day playlists brings good cheer:
