The internet has been clamoring about a new bug that has been found in Gears of War 3. It seems this bug is so bad that it actually corrupts player profiles.
Whenever players try to enter a Horde match with two profiles signed in, the game crashes and one of the profiles actually becomes corrupted and is no longer able to join any game mode. Epic’s forum rep ‘Rykard’ acknowledged the complaints stating that the team over at Epic is “aware of the problem” and promises that they are “working every second toward resolving the issue.”
