Online players of Call of Duty 4 for the Playstation 3 came in for a shock over the weekend as the game servers failed to save their updated rank when they left the game.

Upon logging back into the servers for another play session, many found - to much frustration - that they had reverted back to their previous rank.

Developers Infinity Ward have previously announced that a patch is on the way for both the Playstation 3 and XBox 360 versions of the game, so hopefully these servers issues will be rectified when that is released.
