Kotaku have posted news
that players are having problems with Red Dead Redemption where players, animals and weapons go invisible in the game.
Rockstar told Kotaku that it is "really happy with how well Red Dead Redemption has been received by the community on both platforms so far. We're aware of the issues some people are experiencing on multiplayer and we're working hard to fix them."
They are also asking players to email them their experiences: "if you're having issues please email RDRSupportteam@rockstargames.com. We are also actively on the forums helping people with any questions they may have about the game. Thank you all for your support and we look forward to getting a fix out as quickly as soon as we can."
